Ensure neutron agents & rabbitmq do not restart when upgrading

Browse Source 
This change adds neutron_agent and rabbitmq_all groups to the upgrade
process to ensure new container config does not cause these two
container types to restart.

> While the neutron_agents services have been moved on-to baremetal,
  the old container types will still exist and will have an active
  workload on them. Ensureing we guard against container restarts
  for these services will help deployers maximize uptime during the P>Q
  upgrade.
