lib/streamaggr: limit the the number of concurrent flushes of the aggregate data to the exact number of available CPUs
This should reduce the maximum memory usage during concurrent flushes of the aggregate data

lib/promscrape: reduce the number of concurrently executed processScrapedData calls from 2x of the number of CPUs to the number of CPUs
This should reduce the maximum memory usage for processScrapedData() function by 2x.
The only part, which can be IO-bound in the processScrapedData() is pushData() call,
when it buffers data to persistent queue if the remote storage cannot keep up
with the data ingestion speed. In this case it is OK if the scrape pace will be limited.

lib/promscrape: limit the concurrency during parsing and relabeling the scraped samples
This should reduce memory usage when scraping big number of targets,
since this limits the summary memory usage during concurrent parsing and relabeling
by the number of available CPU cores.

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/promscrape: follow-up after bced9fb978
- Document the bugfix at docs/CHANGELOG.md
- Wait until all the worker goroutines are done in consulWatcher.mustStop()
- Do not log `context canceled` errors when discovering consul serviceNames
- Removed explicit handling of gzipped responses at lib/promscrape/discoveryutils.Client,
  since this handling is automatically performed by net/http.Transport.
  See DisableCompression option at https://pkg.go.dev/net/http#Transport .
- Remove explicit handling of the proxyURL, since it is automatically handled
  by net/http.Transport. See Proxy option at https://pkg.go.dev/net/http#Transport .
- Expliticly set MaxIdleConnsPerHost, since its default value equals to 2.
  Such a small value may result in excess tcp connection churn
  when more than 2 concurrent requests are processed by lib/promscrape/discoveryutils.Client.
- Do not set explicitly the `Host` request header, since it is automatically set by net/http.Client.
- Backport the bugfix to the recently added nomad_sd_configs - see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3367

lib/promscrape/discovery/nomad: follow-up after 48f371a46c
- Remove undocumented `username` and `password` config options from `nomad_sd_config`.
  TODO: probably, remove these options from `consul_sd_config` too?
  These options exist there for backwards compatibility purposes.

- Add __meta_nomad_service_alloc_id and __meta_nomad_service_job_id meta-labels
  These labels contain AllocID and JobID fields for the discovered Nomad services.

- Various typo fixes.

lib/promrelabel: pass query args via query string at /metric-relabel-debug and /target-relabel-debug pages if their length doesnt exceed 1000
This allows copy-n-pasting the url to another browser window and seeing the same result.

The limit in 1000 chars is selected in order to prevent from potential issues with systems
which limit the url length such as Internet Explorer - see https://stackoverflow.com/questions/812925/what-is-the-maximum-possible-length-of-a-query-string

If the limit is exceeded, then query args are sent via POST method and aren't visible in the url.

Got "Failed to upgrade legacy queries Datasource $ds was not found" in
Grafana on operator dashboard.
It's datasource variable was incorrectly named `datasource`.

Also made the rest of the dashboards have homogeneous datasource-variable
names and selections, matching vmagent dashboard.
