lib/storage: make indexdb/tagFilters cache size configurable (#2667)
The default size of `indexdb/tagFilters` now can be overridden via
`storage.cacheSizeIndexDBTagFilters` flag.
Please, be careful with changing default size since it may
lead to inefficient work of the vmstorage or OOM exceptions.

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

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

cdc372bb98 app/vmselect: add -search.noStaleMarkers command-line flag for disabling stale markers handling in queries
This option allows reducing CPU usage a bit when VictoriaMetrics is used
for collecting and processing non-Prometheus data. For example, InfluxDB line protocol, Graphite, OpenTSDB, CSV, etc.

8ee8660ac4 app/vmselect: follow-up for 626073bca8
* Rename -search.maxMetricsPointSearch to -search.maxSamplesPerQuery, so it is more consistent with the existing -search.maxSamplesPerSeries
* Move the -search.maxSamplesPerQuery from vmstorage to vmselect, so it could effectively limit the number of raw samples obtained from all the vmstorage nodes
* Document the -search.maxSamplesPerQuery in docs/CHANGELOG.md

ca75432e66 app/vmselect: do not track queries with less than 1ms execution time at /api/v1/status/top_queries
This should improve the readability and usefullness of the /api/v1/status/top_queries when debugging slow queries
or queries that take too much cpu time.
