Jesse Pretorius 14793d701d Implement rolling upgrades for neutron
Based on [1], this patch implements changes to the playbook
which executes the neutron deployment in a play per host
group, serialised to ensure that:

1. The services are changed in the right order.
2. The API services remain available at all times during
   an upgrade (except when doing a db contract).
3. If services are sharing a host/container then the
   role execution will not execute twice on the same
   host.
