Adds HA controller support + ODL integration and removes ODL installation

Changes include:
 - If ha_flag is set to "true", Control node will be setup in HA for the
   following services: rabbitmq, galera mariadb, keystone, glance, nova,
   cinder, horizon, neutron
 - Required parameters for HA:
   https://gist.github.com/trozet/d3a2a2f88ba750b83008
 - Removes OpenDaylight installation from this puppet manifest.  Will be
   part of a separate commit that only installs OpenDaylight.  This is
   due to the fact that ODL will only run on a single control node in non
   HA mode.
