lib/vmselectapi: properly calculate query timeout
vmselect passes query timeout to vmstorage in seconds.
The commit 20e9598254 treated it as timeout in nanoseconds.
Fix this in order to prevent from the following errors under vmstorage load:

cannot process vmselect request: cannot execute "search_v7": couldn't start executing the request in 0.000 seconds,
since -search.maxConcurrentRequests=... concurrent requests are already executed.

lib/promscrape/discovery/nomad: sync nomad_sd_configs fields with the Prometheus implementation
See the list of configs supported by Prometheus at f88a0a7d83/discovery/nomad/nomad.go (L76-L84)

- Removed "token" option. In can be set either via NOMAD_TOKEN env var or via `bearer_token` config option.
- Removed "scheme" option. It is automatically detected depending on whether the `tls_config` is set.
- Removed "services" and "tags" options, since they aren't supported by Prometheus.
- Added "region" option. If it is missing, then the region is read from NOMAD_REGION env var.
  If this var is empty, then it is set to "global" in the same way as Nomad client does.
  See 865ee8d37c/api/api.go (L297)
  and 865ee8d37c/api/api.go (L555-L556)
- If the "server" option is missing, then it is read from NOMAD_ADDR in the same way
  as Nomad client does - see 865ee8d37c/api/api.go (L294-L296)

This is a follow-up for 8aee209c53

app/vmselect/netstorage: consistently select the sample with the biggest value out of samples with identical timestamps
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3333

This fix is based on https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3620 ,
but doesn't slow down the common case with merging replicated data blocks so significantly.

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

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

- 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.
