lib/streamaggr: enable time alignment for aggregate flushed to multiples of interval
For example, if `interval: 1m`, then data flush occurs at the end of every minute,
while `interval: 1h` leads to data flush at the end of every hour.

Add `no_align_flush_to_interval` option, which can be used for disabling the alignment.

lib/streamaggr: huge pile of changes
- Reduce memory usage by up to 5x when de-duplicating samples across big number of time series.
- Reduce memory usage by up to 5x when aggregating across big number of output time series.
- Add lib/promutils.LabelsCompressor, which is going to be used by other VictoriaMetrics components
  for reducing memory usage for marshaled []prompbmarshal.Label.
- Add `dedup_interval` option at aggregation config, which allows setting individual
  deduplication intervals per each aggregation.
- Add `keep_metric_names` option at aggregation config, which allows keeping the original
  metric names in the output samples.
- Add `unique_samples` output, which counts the number of unique sample values.
- Add `increase_prometheus` and `total_prometheus` outputs, which ignore the first sample
  per each newly encountered time series.
- Use 64-bit hashes instead of marshaled labels as map keys when calculating `count_series` output.
  This makes obsolete https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5579
- Expose various metrics, which may help debugging stream aggregation:
  - vm_streamaggr_dedup_state_size_bytes - the size of data structures responsible for deduplication
  - vm_streamaggr_dedup_state_items_count - the number of items in the deduplication data structures
  - vm_streamaggr_labels_compressor_size_bytes - the size of labels compressor data structures
  - vm_streamaggr_labels_compressor_items_count - the number of entries in the labels compressor
  - vm_streamaggr_flush_duration_seconds - a histogram, which shows the duration of stream aggregation flushes
  - vm_streamaggr_dedup_flush_duration_seconds - a histogram, which shows the duration of deduplication flushes
  - vm_streamaggr_flush_timeouts_total - counter for timed out stream aggregation flushes,
    which took longer than the configured interval
  - vm_streamaggr_dedup_flush_timeouts_total - counter for timed out deduplication flushes,
    which took longer than the configured dedup_interval
- Actualize docs/stream-aggregation.md

The memory usage reduction increases CPU usage during stream aggregation by up to 30%.

app/{vminsert,vmagent}: follow-up after 67a55b89a4
- Document the ability to read OpenTelemetry data from Amazon Firehose at docs/CHANGELOG.md

- Simplify parsing Firehose data. There is no need in trying to optimize the parsing with fastjson
  and byte slice tricks, since OpenTelemetry protocol is really slooow because of over-engineering.
  It is better to write clear code for better maintanability in the future.

- Move Firehose parser from /lib/protoparser/firehose to lib/protoparser/opentelemetry/firehose,
  since it is used only by opentelemetry parser.

deployment: create a separate env for VictoriaLogs (#5857)
* deployment: create a separate env for VictoriaLogs

The new environment consists of the following components:
* VictoriaLogs
* fluentbit for collecting logs and sending to VictoriaLogs
* VictoriaMetrics for scraping and storing metrics from fluentbit and VictoriaLogs
* Grafana with VictoriaLogs datasource for monitoring

-----------------

The motivation for creating a separate environment is to simplify existing environments
and make it easier to update or modify them in future.

lib/httpserver: return back the default value for -http.connTimeout to 2 minutes
It has been appeared that there are VictoriaMetrics users, who rely on the fact that
VictoriaMetrics components were closing incoming connections to -httpListenAddr every 2 minutes
by default. So let's return back this value by default in order to fix the breaking change
made at d8c1db7953 .

app/vmselect: add -search.maxLabelsAPIDuration and -search.maxLabelsAPISeries options for fine-tuning CPU and RAM usage for /api/v1/series , /api/v1/labels and /api/v1/label/.../values
This commit returns back limits for these endpoints, which have been removed at 5d66ee88bd ,
since it has been appeared that missing limits result in high CPU usage, while the introduced concurrency limiter
results in failed lightweight requests to these endpoints because of timeout when heavyweight requests are executed.

  See app/vlselect/logsql/sort_writer.go . Previously random log entries could be returned with each request.
- Document the change at docs/VictoriaLogs/CHANGELOG.md
- Document the `limit` query arg at docs/VictoriaLogs/querying/README.md
- Make the change less intrusive.

it case of churn at `name`  field of users configuration, new metric was created. But previous one wasn't deleted.
It prevented full parsed configuration from being garbace collected.

now all config related metrics are bound to corresponding metrics.Set and unregistered during config reload process.

It also must fix an issue with incorrect values for current concurrent user requests

lib/httpserver: do not close client connections every 2 minutes by default
Closing client connections every 2 minutes doesn't help load balancing -
this just leads to "jumpy" connections between multiple backend servers,
e.g. the load isn't spread evenly among backend servers, and instead jumps
between the servers every 2 minutes.

It is still possible periodically closing client connections by specifying non-zero -http.connTimeout command-line flag.

This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1636997037

deployment/dashboards: fix Storage full ETA panels (#5747)
During background downsampling, rate(vm_deduplicated_samples_total{type="merge"}) could be much bigger than 
rate(vm_rows_added_to_storage_total) and it could last quite some time,
 which causes negative values of Storage full ETA and confuses users, see playground.

Instead of trying to get more accurate results during downsampling, I think it's ok to ignore 
vm_deduplicated_samples_total at all, it's more reasonable to see Storage full ETA increase after downsampling.

The maximum guaranteed precision for raw samples stored in VictoriaMetrics is 12 decimal digits.

app/vmselect: set proper timestamp for cached instant responses (#5723)
* app/vmselect: set proper timestamp for cached instant responses

The change updates `getSumInstantValues` to prefer timestamp
from the most recent results. Before, timestamp from cached series
was used.

The old behavior had negative impact on recording rules as they
were getting responses with shifted timestamps in past.
Subsequent recording or alerting rules fetching results of these
recording rules could get no result due to staleness interval.

lib/promscrape: use the standard net/http.Client instead of fasthttp.Client for scraping targets in non-streaming mode
While fasthttp.Client uses less CPU and RAM when scraping targets with small responses (up to 10K metrics),
it doesn't work well when scraping targets with big responses such as kube-state-metrics.
In this case it could use big amounts of additional memory comparing to net/http.Client,
since fasthttp.Client reads the full response in memory and then tries re-using the large buffer
for further scrapes.

Additionally, fasthttp.Client-based scraping had various issues with proxying, redirects
and scrape timeouts like the following ones:

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1945
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5425
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2794
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1017

This should help reducing memory usage for the case when target returns big response
and this response is scraped by fasthttp.Client at first before switching to stream parsing mode
for subsequent scrapes. Now the switch to stream parsing mode is performed on the first scrape
after reading the response body in memory and noticing that its size exceeds the value passed
to -promscrape.minResponseSizeForStreamParse command-line flag.

do not return raw samples - they both return *calculated* samples at *the given* timestamps.

f5559c038c
lib/storage: do not check the limit for -search.maxUniqueTimeseries when performing /api/v1/labels and /api/v1/label/.../values requests
This limit has little sense for these APIs, since:

- Thses APIs frequently result in scanning of all the time series on the given time range.
  For example, if extra_filters={datacenter="some_dc"} .

- Users expect these APIs shouldn't hit the -search.maxUniqueTimeseries limit,
  which is intended for limiting resource usage at /api/v1/query and /api/v1/query_range requests.

Also limit the concurrency for /api/v1/labels, /api/v1/label/.../values
and /api/v1/series requests in order to limit the maximum memory usage and CPU usage for these API.
This limit shouldn't affect typical use cases for these APIs:

- Grafana dashboard load when dashboard labels should be loaded
- Auto-suggestion list load when editing the query in Grafana or vmui

app/vmalert: fix data race during hot-config reload (#5698)
* app/vmalert: fix data race during hot-config reload

During hot-reload, the logic evokes the group update and rules evaluation
interruption simultaneously. Falsely assuming that interruption happens before
the update. However, it could happen that group will be updated first and only
after the rules evaluation will be cancelled. Which will result in permanent
interruption for all rules within the group.

The fix caches the cancel context function into local variable first. And only after
performs the group update. With cached cancel function we can safely call it without
worrying that we cancel the evaluation for already updated group.

lib/{mergeset,storage}: make background merge more responsive and scalable
- Maintain a separate worker pool per each part type (in-memory, file, big and small).
  Previously a shared pool was used for merging all the part types.
  A single merge worker could merge parts with mixed types at once. For example,
  it could merge simultaneously an in-memory part plus a big file part.
  Such a merge could take hours for big file part. During the duration of this merge
  the in-memory part was pinned in memory and couldn't be persisted to disk
  under the configured -inmemoryDataFlushInterval .

  Another common issue, which could happen when parts with mixed types are merged,
  is uncontrolled growth of in-memory parts or small parts when all the merge workers
  were busy with merging big files. Such growth could lead to significant performance
  degradataion for queries, since every query needs to check ever growing list of parts.
  This could also slow down the registration of new time series, since VictoriaMetrics
  searches for the internal series_id in the indexdb for every new time series.

  The third issue is graceful shutdown duration, which could be very long when a background
  merge is running on in-memory parts plus big file parts. This merge couldn't be interrupted,
  since it merges in-memory parts.

  A separate pool of merge workers per every part type elegantly resolves both issues:
  - In-memory parts are merged to file-based parts in a timely manner, since the maximum
    size of in-memory parts is limited.
  - Long-running merges for big parts do not block merges for in-memory parts and small parts.
  - Graceful shutdown duration is now limited by the time needed for flushing in-memory parts to files.
    Merging for file parts is instantly canceled on graceful shutdown now.

- Deprecate -smallMergeConcurrency command-line flag, since the new background merge algorithm
  should automatically self-tune according to the number of available CPU cores.

- Deprecate -finalMergeDelay command-line flag, since it wasn't working correctly.
  It is better to run forced merge when needed - https://docs.victoriametrics.com/#forced-merge

- Tune the number of shards for pending rows and items before the data goes to in-memory parts
  and becomes visible for search. This improves the maximum data ingestion rate and the maximum rate
  for registration of new time series. This should reduce the duration of data ingestion slowdown
  in VictoriaMetrics cluster on e.g. re-routing events, when some of vmstorage nodes become temporarily
  unavailable.

- Prevent from possible "sync: WaitGroup misuse" panic on graceful shutdown.

This is a follow-up for fa566c68a6 .

 Previously, `ALERTS_FOR_STATE` was generated only for alerts with `for > 0`.
 This behavior differs from Prometheus behavior - it generates ALERTS_FOR_STATE
 time series for alerting rules with `for: 0` as well. Such time series can
 be useful for tracking the moment when alerting rule became active.

app/{vmselect,vmstorage}: return compression of the data passed from vmstorage to vmselect
This reverts cd4f641d32 , since it has been appeared that the disabled compression
for vmstorage->vmselect data increase network bandwidth usage by more than 10x on typical production workloads,
while it decreases CPU usage at vmstorage by up to 10% and improves query latency by up to 10%.

The 10x increase in network usage is too high price for 10% improvements on query latency and vmstorage CPU usage.
This may result in network bandwidth bottlenecks, which can reduce the overall performance and stability
of VictoriaMetrics cluster. That's why return back the vmstorage->vmselect data compression by default.

The vmstorage->vmselect compression can be disabled by passing -rpc.disableCompression command-line flag to vmstorage.
The vmselect->vmselect compression in multi-level cluster setup can be disabled by passing -clusternative.disableCompression command-line flag.

lib/mergeset: really limit the number of in-memory parts to 15
It has been appeared that the registration of new time series slows down linearly
with the number of indexdb parts, since VictoriaMetrics needs to check every indexdb part
when it searches for TSID by newly ingested metric name.

The number of in-memory parts grows when new time series are registered
at high rate. The number of in-memory parts grows faster on systems with big number
of CPU cores, because the mergeset maintains per-CPU buffers with newly added entries
for the indexdb, and every such entry is transformed eventually into a separate in-memory part.

The solution has been suggested in https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5212
by @misutoth - to limit the number of in-memory parts with buffered channel.
This solution is implemented in this commit. Additionally, this commit merges per-CPU parts
into a single part before adding it to the list of in-memory parts. This reduces CPU load
when searching for TSID by newly ingested metric name.

The https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5212 recommends setting the limit on the number
of in-memory parts to 100, but my internal testing shows that much lower limit 15 works with the same efficiency
on a system with 16 CPU cores while reducing memory usage for `indexdb/dataBlocks` cache by up to 50%.

Revert "lib/promscrape: do not store last scrape response when stale markers … (#5577)"
This reverts commit cfec258803.

Reason for revert: the original code already doesn't store the last scrape response when stale markers are disabled.
The scrapeWork.areIdenticalSeries() function always returns true is stale markers are disabled.
This prevents from storing the last response at scrapeWork.processScrapedData().

It looks like the reverted commit could also return back the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3660

* lib/promscrape/kubernetes: prevent from stopping groupWatcher when there are in-flight apiWatcher.mustStart() calls

groupWatcher is stopped if it has zero registered apiWatchers during 14 seconds.
But such a groupWatcher can be still in use if apiWatcher for `role: endpoints` or `role: endpointslice`
is being registered and the discovery of the associated `pod` and/or `service` objects takes longer
than 14 seconds - see the beginning of groupWatcher.startWatchersForRole() function for details.

Track the number of in-flight calls to apiWatcher.mustStart() and prevent from stopping the associated groupWatcher
if the number of in-flight calls is non-zero.

P.S. postponing the discovery of `pod` and/or `service` objects associated with `endpoints` or `endpointslice` roles
isn't the best solution, since it slows down initial discovery of `endpoints` and `endpointslice` targets.

docs: remove slug from Grafana dashboard URLs
Each Grafana dashboard has unique ID which can be used to fetch the dashboard
from grafana.com: https://grafana.com/grafana/dashboards/11176
The same dashboard can be accessed via URL with slug: https://grafana.com/grafana/dashboards/11176-victoriametrics-cluster/
But using slug implies that any change to dashboard name will break the link.
So it is better to just use ID, so the dashboard URL will never break.

This is follow-up for ff33e60a3d

docs/setup-size: rm tolerable churn rate %
It is likely this value was borrowed from panel `Slow inserts` panel
from Grafana dasbhoard for VM single/cluster installations. This is a mistake.
There is no such thing as "tolerable churn rate", as tolerancy depends on the amount
of allocated resources.

Although, it is unclear what is meant by 5%. If it refers to 5% of new time series per second,
then such churn rate is extremely high. It would mean that the avg life of a time series is 20s.

app/vmselect: properly calculate start param for queries with too big look-behind window (#5630)
Properly determine time range search for instant queries with too big look-behind window like `foo[100y]`.
