Update docs (#2566)
* deployment/docker: pass `-buildvs=false` to `go build` for production builds

This should resolve the `error obtaining VCS status: exit status 128` error
when the environment contains incorrect version of git or has incorrect access rights
to the directory with VictoriaMetrics source code.

See the following links for additional info:
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2508#issuecomment-1117126702 ,
- https://github.com/google/ko/issues/672
- https://github.com/golang/go/issues/49004

* lib/netutil: limit the number of concurrently established connections when calling ConnPool.Get()

This should reduce potential spikes in the number of established connections in the following cases:
- when the connection establishing procedure becomes temporarily slow
- after a temporary spike in the rate of ConnPool.Get() calls

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2552

* docs/CHANGELOG.md: document c8af625bcc

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1322#issuecomment-1120276146

* docs/Cluster-VictoriaMetrics.md: typo fix: `by by` -> `by`

* docs: add `resource usage limits` docs, which describe fine-grained tuning for various resource usage limits

* docs/Cluster-VictoriaMetrics.md: the `/api/v1/label/.../values` query can take CPU and ram at both vmstorage and vmselect

* Update root Readme and root vmagent readme

lib/promscrape: reduce memory usage if -promscrape.noStaleMarkers command-line flag is passed
Do not store in memory the response from the last scrape per each target if -promscrape.noStaleMarkers option is enabled.
This should reduce memory usage when the scraped targets return large responses.

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.

d6bd956930 lib/promrelabel: add keep_metrics and drop_metrics actions to relabeling rules
These actions simlify metrics filtering. For example,

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

would leave only metrics with `foo`, `bar` and `baz` names, while the rest of metrics will be deleted.

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

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.
