rbd: add capability to automatically enable read affinity

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