Kevin Carter 1d290828b9 RFC1034/5 hostname upgrade

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).
