31d04fb5df Revert "lib/logger: prevent from blocking when log output isn't consumed in timely manner" 
This reverts commit e3c462f08a.

Reason to revert: this leaves incomplete logs on app shutdown.

0ed9258545 lib/{mergeset,storage}: log info message when both source and destination part paths from txn are missing during startup

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.

20812008a7 lib/storage: remove metricID with missing metricID->metricName entry 
The metricID->metricName entry can be missing in the indexdb after unclean shutdown
when only a part of entries for new time series is written into indexdb.

Recover from such a situation by removing the broken metricID. New metricID
will be automatically created for time series with the given metricName
when new data point will arive to it.

a7125a5b7b lib/backup: remove flock.lock file in empty dirs 
This fixes an issue when VictoriaMetrics doesn't see the restored data after the following operations:

1. Stop VictoriaMetrics.
2. Delete `<-storageDataPath>` dir.
3. Start VictoriaMetrics, then stop it.
4. Restore data from backup with `vmrestore`.
5. Start VictoriaMetrics.

`vmrestore` didn't delete properly empty dirs in `<-storageDataPath>/indexdb` because of the remaining `flock.lock` files in these dirs.
