4862e93024 lib/fs: try harder with directory removal on NFS in the event of temporary lock 
Do not give up after 11 attempts of directory removal on laggy NFS.

Add `vm_nfs_dir_remove_failed_attempts_total` metric for counting the number of failed attempts
on directory removal.

Log failed attempts on directory removal after long sleep times.

3308279c4e lib/storage: remove outdated comment on maxRowsPerSmallPart 
The commend became outdated after the commit ed6ac1a5df027f0dfc22448e3b27c26b6f77c67a,
which stops merging of small parts on graceful shutdown instead of waiting
for their completion.

This should reduce the amount of RAM required for processing time series
with non-zero churn rate.

The previous cache behavior can be restored with `-cache.oldBehavior` command-line flag.

0f2ecde0e6 lib/encoding: improve gauge series detection 
- Series with negative values are always gauges
- Counters may only have increasing values with possible counter resets

This should improve compression ratio for gauge series which
were previously mistakenly detected as counters.
