Based on [1], this patch implements changes to the playbook which executes the nova 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. 3. If services are sharing a host/container then the role execution will not execute twice on the same host.
