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.

5d8d110010 lib/fs: atomically create file with the given contents on WriteFileAtomically
This should prevent from `transaction` and `metadata.json` files corruption
on unclean shutdown such as OOM, `kill -9`, power loss, etc.

c1276edab5 lib/fs: panic with fatal error when directories cannot be removed
Unremoved directories may lead to inconsistent data directory,
so VictoriaMetrics will fail to start next time.

So panic on the first error when trying to remove directory in order
to simplify recover process.
