This commit makes use of crush location labels from node
labels to supply `crush_location` and `read_from_replica=localize`
options during mount. Using these options, cephfs
will be able to redirect reads to the closest OSD,
improving performance.

from the rest of the cluster - new provisioner leader
is elected in ~15 seconds, while it may take up to
5 minutes for StatefulSet to start a new replica.
