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.
