Temporarily use heat's heat-keystone-setup-domain

Heat in juno relies on keystone domains, however our lxc keystone module
does not support this functionality (which requires keystone v3).  Our
long-term goal should be to update our keystone ansible module however
there are larger implications in moving that module over to using v3
for all calls.

This commit bypasses using the keystone module and shells out to
heat-keystone-setup-domain which sets up the keystone domain and domain
user for us.

Temporarily use heat's heat-keystone-setup-domain
Updated Neutron for the Juno release.

Changes in config were made to allow for automatic HA failover of Neutron Routers. (input from Phill Hopkins)
Removes the ATT L3 HA tool as this functionality is now baked into Neutron proper.
Removed package and git vars from group_vars/neutron_all.yml and change the plays to use the values in repo_pacakge/neutron.yml
removed redundant tasks in all neutron plays.
