3149af624d lib/storage: reduce the maximum number of concurrent merge workers to GOMAXPROCS/2 
Previously the limit has been raised to GOMAXPROCS, but it has been appeared that this
increases query latencies since more CPUs are busy with merges.

While at it, substitute `*MergeConcurrencyLimitCh` channels with simple integer limits.

29bbab0ec9 lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected 
The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts.

Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon,
which should return CPU and disk IO usage to normal levels.

Previously the `vm_slow_row_inserts_total` metric may be incremented multiple times for different data points per a single time series,
while only a single increment is needed when inserting the first data point for this time series.

754eac676d lib/storage: prevent possible race condition when all the goroutines exit Storage.AddRows, before goroutines other goroutines are blocked on searchTSIDsCond inside Storage.searchTSIDs 
This condition may occur after the following sequence of events:

1) A goroutine enters the loop body when len(addRowsConcurrencyCh) == cap(addRowsConcurrencyCh) inside Storage.searchTSIDs.
2) All the goroutines return from Storage.AddRows.
3) The goroutine from step 1 blocks on searchTSIDsCond.Wait() inside the loop body.

The goroutine remains blocked until the next call to Storage.AddRows, which calls searchTSIDsCond.Signal().
This may take indefinite time.

be0ab4fbfe lib/storage: reset MetricName->TSID cache after marking metricIDs as deleted 
This is a follow-up commit after 12b16077c4 ,
which didn't reset the `tsidCache` in all the required places.
This could result in indefinite errors like:

    missing metricName by metricID ...; this could be the case after unclean shutdown; deleting the metricID, so it could be re-created next time

Fix this by resetting the cache inside deleteMetricIDs function.

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.

605711bde5 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.

```

7335743d57 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.

fe58462bef 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.

0bff96fe4b 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.

b0131c79b6 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[.]*".
