fa3bcf220f lib/storage: remove stale parts as soon as they go outside the configured retention 
Previously such parts could remain undeleted for long durations until they are merged with other parts.
This should help for `-retentionPeriod` values smaller than one month.

While at it, fix a bug, which could prevent from finding time series with names containing dots (aka Graphite-like names
such as `foo.bar.baz`).

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.

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.

Fix this by resetting the cache inside deleteMetricIDs function.

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,

is achieved when the number of concurrent calls to Storage.AddRows is limited to the number of CPUs,
i.e. to GOMAXPROCS.

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[.]*".
