When gathering the list of local OSD ids, the charm would consider
the entries under '/var/lib/ceph/osd/ceph-XXX' where 'XXX" was the
OSD id. However, if an entry under that directory isn't mounted,
then the OSD that would represent that entry should be discarded,
as it's no longer active. This patchset thus filters those entries
by looking for them in the mount points.

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.
