c8ea697db8 lib/storage: de-duplicate tags in MetricName.sortTags 
Leave only the last tag among tags with duplicate keys. This is needed for reliable addition of extra_labels
during data ingestion. See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1007 for details.

e7959094f6 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.

e4303d3d21 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.

This is a follow-up commit after 12b16077c4 ,

    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.

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.

a7797dae09 lib/storage: fix Graphite wildcard matching, which has been broken in v1.36.0 
v1.36.0 always returns empty responses for Graphite wildcards like the following

   {__name__=~"foo\\.[^.]*\\.bar\\.baz"}

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[.]*".
