vmalert: support /rules path for Grafana's ngalert requests (#2593)
Unexpectedly, Grafana makes an extra request to `/rules`
handler in addition to `/api/v1/rules` calls in alerts UI.
This happens only for Grafana versions older than 8.5.*.
Apparently, this is related to support of other monitoring
systems.
Prometheus responds with `text/html` content for UI page `/rules`
to such requests. Actually, returning just a blank page with
SC=200 works as well.

Returning actual response of `/api/v1/rules`
results in error in Grafana since it expects a `yaml` (?) in response.
So we add a placeholder to `vmalert`.

Export "null" in jsonl instead of NaN (#2518)
* Export "null" in jsonl instead of NaN

The NaN appeared because of staleness markers that were added for compatibility. I think it's better to use json `null`, implemented here.

Also maybe it also makes sense to add a flag like `?skip-staleness-markers=true` to `/export`, to skip nulls at all?

* Update app/vmselect/prometheus/export.qtpl

* app/vmselect/prometheus/export.qtpl.go: `make quicktemplate-gen`

app/vmselect/netstorage: report vmstorage errors to vmselect clients even if partial responses are allowed
If a vmstorage is reachable and returns an application-level error to vmselect,
then such error must be returned to the caller even if partial responses are allowed,
since it usually means cluster mis-configuration.

Partial responses may be returned only if some vmstorage nodes are temporarily unavailable.

Consul SD - update services on the watcher's start (#2202)
* lib/discovery/consul: update services on the watcher's start

Previously, watcher's start was only initing goroutines for discovery
but not waiting for the first iteration to end. It means first Consul
discovery wasn't returning discovered targets until the next iteration.

The change makes the watcher's start blocking until we get first discovery
iteration done and all registries updated.

lib/index: reduce read/write load after indexDB rotation (#2177)
* lib/index: reduce read/write load after indexDB rotation

IndexDB in VM is responsible for storing TSID - ID's used for identifying
time series. The index is stored on disk and used by both ingestion and read path.

IndexDB is stored separately to data parts and is global for all stored data.
It can't be deleted partially as VM deletes data parts. Instead, indexDB is
rotated once in `retention` interval.

The rotation procedure means that `current` indexDB becomes `previous`,
and new freshly created indexDB struct becomes `current`. So in any time,
VM holds indexDB for current and previous retention periods.
When time series is ingested or queried, VM checks if its TSID is present
in `current` indexDB. If it is missing, it checks the `previous` indexDB.
If TSID was found, it gets copied to the `current` indexDB. In this way
`current` indexDB stores only series which were active during the retention
period.

To improve indexDB lookups, VM uses a cache layer called `tsidCache`. Both
write and read path consult `tsidCache` and on miss the relad lookup happens.

When rotation happens, VM resets the `tsidCache`. This is needed for ingestion
path to trigger `current` indexDB re-population. Since index re-population
requires additional resources, every index rotation event may cause some extra
load on CPU and disk. While it may be unnoticeable for most of the cases,
for systems with very high number of unique series each rotation may lead
to performance degradation for some period of time.

This PR makes an attempt to smooth out resource usage after the rotation.
The changes are following:
1. `tsidCache` is no longer reset after the rotation;
2. Instead, each entry in `tsidCache` gains a notion of indexDB to which
they belong;
3. On ingestion path after the rotation we check if requested TSID was
found in `tsidCache`. Then we have 3 branches:
3.1 Fast path. It was found, and belongs to the `current` indexDB. Return TSID.
3.2 Slow path. It wasn't found, so we generate it from scratch,
add to `current` indexDB, add it to `tsidCache`.
3.3 Smooth path. It was found but does not belong to the `current` indexDB.
In this case, we add it to the `current` indexDB with some probability.
The probability is based on time passed since the last rotation with some threshold.
The more time has passed since rotation the higher is chance to re-populate `current` indexDB.
The default re-population interval in this PR is set to `1h`, during which entries from
`previous` index supposed to slowly re-populate `current` index.

The new metric `vm_timeseries_repopulated_total` was added to identify how many TSIDs
were moved from `previous` indexDB to the `current` indexDB. This metric supposed to
grow only during the first `1h` after the last rotation.

* Binary operations with `on()`, `without()`, `group_left()` and `group_right()` modifiers.
  For example, foo{a="b"} on (a) + bar is now optimized to foo{a="b"} on (a) + bar{a="b"}
* Multi-level binary operations. For example, foo{a="b"} + bar{x="y"} + baz{z="q"}
  is now optimized to foo{a="b",x="y",z="q"} + bar{a="b",x="y",z="q"} + baz{a="b",x="y",z="q"}
* Aggregate functions. For example, sum(foo{a="b"}) by (c) + bar{c="d"}

lib/storage: convert alternate regexps into Graphite wildcards inside __graphite__ pseudo-label

This allows using multi-value Grafana template variables such as `{__graphite__=~"foo.($app)"}`.

lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice
This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode
at the cost of the increased memory usage, since now the potentially big response is kept
in the lastScrape byte slice per each scrapeWork.

In practice the memory usage increase shouldn't be big, since the response size
is usually much smaller than the parsed metrics from this response after the relabeling,
which usually adds a big pile of target-specific labels per each metric.

f3e89754a9 lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric
Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics.

The main idea is to perform the calculations on scrape_series_added and series_limit
only if the set of metrics exposed by the target has been changed.
Scrape targets rarely change the set of exposed metrics,
so this optimization should reduce CPU usage in general case.

The commit also makes possible to split long regexps into multiple lines. For example, the following config is equivalent to the config above:

- action: keep_metrics
  regex:
  - foo
  - bar
  - baz

d5622b32e2 lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets
Store the scraped response body instead of storing the parsed and relabeld metrics.
This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics.
This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics.

This should also reduce CPU usage, since the marshaling of the parsed
and relabeld metrics has been substituted by response body copying.

8f973e34fb lib/workingsetcache: properly switch to whole mode
Previously the switch from `split` to `whole` mode had been performed too early,
e.g. when the current cache size became bigger than 1/4 of the allowed cache size.

Now it is performed when the current cache size becomes bigger than 1/2 of the allowed cache size.

This change can reduce memory usage for data ingestion path when big number of active time series are ingested.

84fb59b0ba lib/storage: move deletedMetricIDs set from indexDB to Storage
This makes consitent the list of deleted metricIDs when it is used from both the current indexDB and the previous indexDB (aka extDB).
This should fix the issue, which could lead to storing new samples under deleted metricIDs after indexDB rotation.
See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136 .

Thanks to @tangqipengleoo for the initial analysis and the pull request - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

This commit resolves the issue in more generic way compared to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

The downside of the commit is the deletedMetricIDs set isn't cleaned from the metricIDs outside the retention. It needs app restart.
This should be OK in most cases.

ce9e163e94 lib/httpserver: stop the process on panics in request handlers
Panics may leave the process in inconsistent state. That's why it is better to stop the process after the panic
instead of recovering from the panic. Unfortunately, the standard net/http.Server recovers panics in request handlers.
See https://github.com/golang/go/issues/16542 . That's lib/httpserver must stop the process on itself after the panic.

docs: update docs ordering and formatting (#1192)
The major change is adding `sort` directive to docs. For those docs which are copied
from internal packages `sort` is added via makefile command. For the rest it is added
manually since they're updated manually as well.

The rest of changes is connected with markdown formatting. For example, changing headers
in some files (`##` => `#`) makes navigation on .github.io to look better. This especially
useful for `changelog` docs.

Table of contents for `vmctl` is dropped, since we already have it autogenerated on .github.io.

No link changes expected. The corresponding PR to `cluster` branch will be made in follow-up PR.

f010d773d6 lib/promscrape/discovery/kubernetes: synchronously load Kubernetes objects on first access
Remove async registration of apiWatchers, since it breaks discovering `role: endpoints` and `role: endpointslices` targets,
which depend on pod and service objects.

There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change,
since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain
ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.

This adds the following new metrics for each VictoriaMetrics app:

* process_resident_memory_anonymous_bytes - the RSS share for memory allocated by the process itself.
  This share cannot be freed by the OS, so it must be taken into account by OOM killer.

* process_resident_memory_pagecache_bytes - the RSS share for page cache memory (aka memory-mapped files).
  This share can be freed by the OS at any time, so it must be ignored by OOM killer.
