Adds Ceph cluster creation for controllers
PATCHSET3: fixes whitepsace
Uses ceph_deploy.pp to create a Ceph cluster that is integrated into
OpenStack. The current model is 1 OSD and 1 Ceph mon per controller,
clustered together, resulting in 3 OSDs and 3 Mons. The network used
for storage is optional, provided by storage_iface. If that variable is
unset, then storage network will run on private network.
