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 .

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 .

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`.

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.

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.
