7830c10eb2 lib/{storage,mergeset}: gradually remove stale entries from block cache and index caches 
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`.

in order to preserve sort order of mergeset blocks.

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.

5d8d110010 lib/fs: atomically create file with the given contents on WriteFileAtomically
