Alan Meadows ccea6b4df5 Convert ceph to utilize hostNetworking
This enhances the stability and recovery of ceph by leveraging
hostNetworking for monitors as well as OSDs, and enables the
K8S_HOST_NETWORK variable within ceph-docker.  This enhancement should
allow recovery of monitors from a complete downed cluster.

Additionally, ceph's generic "ceph-storage" node label has been
split out for mon, mds, and osd.
