Adds HA and Ceph-Cinder backend to compute node

Adds HA and Ceph-Cinder backend to compute node
PATCH SET3: Fixes whitespace: L21, L26

Changes to the module include:
 - ha_flag used to indicate mandatory HA parameters, such as vips for
   each openstack service, instead of one single controller IP.
 - Ceph variables introduced and defaulted for use with Cinder.  Control
   node also uses these same defaults, along with the Ceph installer.
 - Minor fix for vnc proxy to work inside of Horizon for compute node
   when consoling in.
