Update rbd-mirror key caps to use the rbd-mirror-peer mon profile.
This adds required config get/set permissions for the rbd-mirror
daemon.
Also add permission to use the service {dump,status} mon commands;
these are not required by the rbd-mirror daemon but are needed by
the charm to check pool mirror status.

Helper functions for the ceph charms. This library has shared functionality that is used in the ceph-mon, ceph-osd and ceph
charms. Anything that needs to be shared across the ceph charms should live here.
