lib/flagutil: specify additional description for all Array type flags (#620)
Array type flag is now defined as `value` type in flag description when printed.
This change adds additional description to every Array type flag so it would be
clear what exact type is used:
```
  -remoteWrite.urlRelabelConfig array
        Optional path to relabel config for the corresponding -remoteWrite.url
        Supports array of values separated by comma or specified via multiple flags.
```

lib/persistentqueue: add vm_persistentqueue_bytes_pending metric (#619)
Metric `vm_persistentqueue_bytes_pending` is a gauge that shows current amount
of bytes in persistentqueue flushed on disk as a difference between write and read
offsets. This metric is very similar to `vmagent_remotewrite_pending_data_bytes`
except of accounting for bytes in-memory.

Extend metric vm_promscrape_targets with status label (#615)
The change to `vm_promscrape_targets` metric suppose to improve observability
for `vmagent` so it will be possible to track how many targets are up or down
for every specific scrape group:
```
vm_promscrape_targets{type="static_configs", status="down"} 1
vm_promscrape_targets{type="static_configs", status="up"} 2
```

cb92113632 lib/storage: limit the maximum concurrency for data ingestion to GOMAXPROCS
Previously the concurrency has been limited to GOMAXPROCS*2. This had little sense,
since every call to Storage.AddRows is bound to CPU, so the maximum ingestion bandwidth
is achieved when the number of concurrent calls to Storage.AddRows is limited to the number of CPUs,
i.e. to GOMAXPROCS.

12b16077c4 lib/storage: reset MetricName->TSID cache after deleting time series
This should prevent from adding new data points to deleted time series
without the need to check for the deleted time series.

This improves ingestion performance a bit when the `deleted time series ids` aka `dmis` set
contains big number of time series.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/596

6daa5f7500 lib/storage: prioritize data ingestion over heavy queries
Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream.
Prevent this by delaying queries' execution until free resources are available for data ingestion.

Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources
for data ingestion and/or for executing heavy queries.

a7797dae09 lib/storage: fix Graphite wildcard matching, which has been broken in v1.36.0

Temporary workaround for v1.36.0 is to add `[^.]*` to the end of the regexp.

d186472081 lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz
Add index for reverse Graphite-like metric names with dots. Use this index during search for filters
like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case.

This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter,
i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".

099e44005b lib/httpserver: add -http.shutdownDelay flag for a grace period before http server shutdown
The http server returns 503 non-OK error at `/health` page during grace period,
so load balancers in front of the http server could re-route incoming requests
to other servers.

787fcfba0c lib/httpserver: reduce typical duration for http server graceful shutdown

because of imporperly set timeouts in setNetworkTimeout.
Now typical duration for graceful shutdown should be reduced to less than 5 seconds.
