7836ad8907 lib/mergeset: skip createing temporary part objects when merging source inmemory parts 
This should reduce CPU usage when adding new entries to inverted index.
This should alos prevent from creating stalled cleaner goroutines for the created temporary parts,
since they were never closed.

This should fix the following issue: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/316 .

eceaf13e5e lib/{storage,mergeset}: use time.Ticker instead of time.Timer where appropriate 
It has been appeared that time.Timer was used in places where time.Ticker must be used instead.
This could result in blocked goroutines as in the https://github.com/VictoriaMetrics/VictoriaMetrics/issues/316 .

This should reduce memory usage in the long run when old blocks and indexes
aren't accessed anymore.

0ed9258545 lib/{mergeset,storage}: log info message when both source and destination part paths from txn are missing during startup 
This is expected condition after unclean shutdown (OOM, hard reset, `kill -9`) on NFS disk.

72345eb5bd lib/{mergeset,storage}: make sure pending transaction deletions are finished before and after runTransactions call. 
`runTransactions` call issues async deletions for transaction files. The previously issued transaction deletions
can race with the next call to `runTransactions`. Prevent this by waiting until all the pending transaction
deletions are funished in the beginning of `runTransactions`. Also make sure that all the pending transaction
deletions are finished before returning from `runTransactions`.

638a5cbb16 lib/{mergeset,storage}: remove transaction files only after the mentioned dirs are really removed 
This should fix the issue on NFS when incompletely removed dirs may be left
after unclean shutdown (OOM, kill -9, hard reset, etc.), while the corresponding transaction
files are already removed.

aebc45ad26 lib/{mergeset,storage}: do not cache inverted index blocks containing tag->metricIDs items 
This should reduce the amounts of used RAM during queries with filters over big number of time series.

b986516fbe lib/storage: create and use lib/uint64set instead of map[uint64]struct{} 
This should improve inverted index search performance for filters matching big number of time series,
since `lib/uint64set.Set` is faster than `map[uint64]struct{}` for both `Add` and `Has` calls.
See the corresponding benchmarks in `lib/uint64set`.

0686ac52c3 lib/{storage,mergeset}: merge tag->metricID rows into tag->metricIDs rows for common tag values 
This should improve lookup performance if the same `label=value` pair exists
in big number of time series.
This should also reduce memory usage for mergeset data cache, since `tag->metricIDs` rows
occupy less space than the original `tag->metricID` rows.
