Revert "app/vmselect: make vmselect resilient to absence of cache folder (#5987)"
This reverts commit cb23685681.

Reason for revert: the "fix" may hide programming bugs related to incorrect creation of folders
before their use. This may complicate detecting and fixing such bugs in the future.

There are the following fixes for the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5985 :
- To configure the OS to do not drop data from the system-wide temporary directory (aka /tmp).
- To run VictoriaMetrics with -cacheDataPath command-line flag, which points to the directory,
  which cannot be removed automatically by the OS.

The case when the user accidentally deletes the directory with some files created by VictoriaMetrics
shouldn't be considered as expected, so VictoriaMetrics shouldn't try resolving this case automatically.
It is much better from operation and debuggability PoV is to crash with the clear `directory doesn't exist` error
in this case.

app/vmagent: properly shutdown when -maxIngestionRate limit is reached
The remotewrite.Stop() expects that there are no pending calls to TryPush().
This means that the ingestionRateLimiter.Register() must be unblocked inside TryPush() when calling remotewrite.Stop().
Provide remotewrite.StopIngestionRateLimiter() function for unblocking the rate limiter before calling the remotewrite.Stop().

While at it, move the rate limiter into lib/ratelimiter package, since it has two users.
Also move the description of the feature to the correct place at docs/CHANGELOG.md.
Also cross-reference -remoteWrite.rateLimit and -maxIngestionRate command-line flags.

docs/CHANGELOG.md: remove the update notes regarding converting custom HTTP header keys to canonical form
Custom HTTP headers are set via net/http.Header.Set or net/http.Header.Add functions.
These functions always convert header keys to canonical form. So the change at b577413d3b
isn't visible to users of VictoriaMetrics components.

There is no need in documenting this change at docs/CHANGELOG.md, since it doesn't give any useful information to users.

Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com>

* lib/storage: consistently use MaxTimestamp to determine deduplication/downsampling rules

Using MinTimestamp leads to applying downsampling to parts which are only partially covered by downsampling rule.
For example, partition covers range [1000-2000]. At t=2100 and rule offset 500 data with t=2100-500 => 1600 must be downsampled. The range check against MinTimestamp evaluates to true even though partition contains range which must not be downsampled - [1600:2000].

Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com>

* Follow-up

- Apply the first matching downsampling period if multiple filters match the given time series.
  This allows fine-tuning the downsampling config for the specific needs.
- Take into account downsampling filters during search queries.
- Reduce the difference between community and enterprise branches. This should simplify further maintenance of these branches.
- Properly parse series filters with colons inside them.
- Document the feature at docs/CHANGELOG.md.

app/vmagent/remotewrite: follow-up for 166b97b8d0 and b6bd9a97a3
- Make the configuration more clear by accepting the list of ignored labels during sharding
  via a dedicated command-line flag - -remoteWrite.shardByURL.ignoreLabels.
  This prevents from overloading the meaning of -remoteWrite.shardByURL.labels command-line flag.

- Removed superfluous memory allocation per each processed sample if sharding by remote storage is enabled.

app/vmalert: respect batch size limit for remote write on shutdown (#6039)
During shutdown period of vmalert, remotewrite client retrieve all pending time series from buffer queue, compose them into 1 batch and execute remote write.

This final batch may exceed the limit of -remoteWrite.maxBatchSize, and be rejected by the receiver (gateway, vmcluster or others).

This changes ensures that even during shutdown vmalert won't exceed the max batch size limit for remote write
destination.

app/vmselect: make vmselect resilient to absence of cache folder (#5987)
vmselect uses a cache folder in file system for two purposes:
1. Storing rollup cache results on shutdown;
2. Storing temporary search results from vmstorage during query executions.

It could happen that cache folder is deleted accidentally by user, or by OS
during cleanup routines. This would cause vmselect to:
1. panic on /metrics call, because `MustGetFreeSpace` will fail;
2. return query error user, as it won't be able to store temporary search results.

The changes in this commit are the following:
1. Make `MustGetFreeSpace` to try re-creating the cache folder if it is missing;
2. Make vmselect to try re-creating the cache folder if it can't persist tmp search
results.

lib/storage: wait for up to 60 seconds before deciding to delete metricID entries from indexdb if metricID->metricName entry is missing during search
The metricID->metricName entry can remain invisible for search for some time after registering new metricName.
This is expected condition. So wait for up to 60 seconds in the hope that the metricID->metricName
entry will become visible before deleting all the entries from indexdb, which are associated with the given metricID.

app/vmselect/prometheus: do not drop match[] filters if -search.ignoreExtraFiltersAtLabelsAPI flag is set
The `match[]` filter is mandatory at /api/v1/series, so it mustn't be dropped here.

There is no sense in dropping `match[]` filter together with `extra_label` and `extra_filters[]`
at /api/v1/labels and /api/v1/label/.../values if -search.ignoreExtraFiltersAtLabelsAPI commnad-line flag is set,
since:
- the `match[]` filter triggers slow path at these APIs;
- the `extra_label` and `extra_filters[]` filters narrow down the number of matched time series,
  so they improve performance comparing to the case when only `match[]` filter is left,
  while `extra_label` and `extra_filters[]` filters are dropped.

- 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%.
