This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
The changes created here allow for upgrades to take place without impacting cluster availability in cases where a a service may be dependent on a non-compliant hostname(s). Upgrade playbook has been added for ensuring hostname aliases are correctly created. Specific entries for nova, heat, cinder neutron, galera and rabbitmq have been added to ensure all nodes are able to contact all other nodes using a potentially non-compliant hostname entry. To make setting the domain name easy across the cluster a new global variable has been created ``openstack_domain``. This variable has a default value of "openstack.local". Because the initial release of Mitaka (13.0.0) did not contain the RFC1034/5 updates these changes are needed to guarentee clusters deployed on our initial release are upgradable to Newton (14.0.0).
