vmselect/promql: check for deadline in count_values fn (#3806) 
* vmselect/promql: check for deadline in `count_values` fn

`count_values` could be very slow during the data processing.
Checking for deadline between iterations supposed to reduce
probability of exceeding `search.maxQueryDuration`.

The change also adds a new trace record, which captures the time
spent in aggregation function. Before that, the trace for aggr funcs
could be confusing since it doesn't account for all the places where
time was spent.

app/vmauth: improve load balancing by sending incoming requests to backends with the lowest number of concurrent requests 
While at it, stop sending requests to unavailable backend for 3 seconds
before the next attempt. This should reduce the amounts of useless work
and the number of useless network packets when the backend is temporarily unavailable.

Clarifications between standalone/cluster ingestion endpoints (#3771) 
docs: clarifications between standalone/cluster ingestion endpoints

This is an attempt to make it a bit clearer to the user that the cluster version ingestion URLs are different from the standalone ones.  I have also changed the order of the list items to make it a bit clearer and hopefully stop the user simply inferring that `/prometheus/api/v1` is only related to Prometheus data.

docs/Cluster-VictoriaMetrics.md: move Naive_cluster_scheme.png from the docs/assets/images/ folder into docs/ folder and add Cluster-VictoriaMetrics_ prefix to the image name 
The docs/assets folder should be used only for assets specific to docs generation at https://docs.victoriametrics.com, e.g. css, js and images.

All the other assets related to specific docs should be placed in the same folder as the corresponding *.md file.
These assets should have the same name prefix as the corresponding doc file name. This simplifies tracking the lifetime of these assets.
For example, if the doc is removed, it is very easy to remove all assets associated with it with a simple `rm -rf docs/doc-name*` command.

This also simplifies generating correct urls for doc-specific assets from both https://docs.victoriametrics.com
and from https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/ - just refer to the asset name without any directory prefixes.

lib/writeconcurrencylimiter: improve the logic behind -maxConcurrentInserts limit 
Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.

It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.

lib/vmselectapi: limit the number of concurrently executed requests 
This should prevent from out of memory errors when big number of vmselect
nodes send many concurrent requests to vmstorage

The limit can be controlled at vmstorage via the following command-line flags:
- search.maxConcurrentRequests
- search.maxQueueDuration

lib/storage: subsitute searchTSIDs functions with more lightweight searchMetricIDs function 
The searchTSIDs function was searching for metricIDs matching the the given tag filters
and then was locating the corresponding TSID entries for the found metricIDs.

The TSID entries aren't needed when searching for time series names (aka MetricName),
so this commit removes the uneeded TSID search from the implementation of /api/v1/series API.
This improves perfromance of /api/v1/series calls.

This commit also improves performance a bit for /api/v1/query and /api/v1/query_range calls,
since now these calls cache small metricIDs instead of big TSID entries
in the indexdb/tagFilters cache (now this cache is named indexdb/tagFiltersToMetricIDs)
without the need to compress the saved entries in order to save cache space.

This commit also removes concurrency limiter during searching for matching time series,
which was introduced in 8f16388428, since the concurrency
for all the read queries is already limited with -search.maxConcurrentRequests command-line flag.

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

8a6a36429a app/vminsert/netstorage: disable rerouting by default 
Production clusters work more stable with the disabled rerouting during rolling restarts and/or
during spikes in time series churn rate. So it would be better disabling the rerouting by default.

The re-routing can be enabled by passing `-disableRerouting=false` command-line flag to `vminsert` nodes.
