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.

lib/promscrape: add -promscrape.minResponseSizeForStreamParse command-line option for automatic switching to stream parsing mode when scraping targets with big responses 
This should reduce memory usage when vmagent scrapes targets with non-uniform response sizes.
This is common case in Kubernetes monitoring.
