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.

lib/persistentqueue: add vm_persistentqueue_bytes_pending

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.

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.

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[.]*".
