Andy McCrae 966ea269c9 Add nova-placement-api service and cell_v2 setup
This patch adds Nova requirements for Ocata:
* Nova Placement API running as uwsgi with Nginx.
* cell_v2 setup for cell0 and cell1
* All required settings for these services with sane defaults

It fixes up some ordering for DB operations:
* online_db_migrations should only happen after a full upgrade.
* Cell setup needs to happen after api_db sync but before db sync.
* Discover_hosts for cell_v2 needs to happen after compute is restarted

This adds functionality to allow uwsgi apps in the init scripts:
* Allowing the "--log" line to be adjusted.
* Setting the condition value so that only enabled services are deployed
* Fixes a bug for program_override which mean this value was never being
used.

features:
- The ``nova-placement`` service is now configured
by default. ``nova_placement_service_enabled``
can be set to ``False`` to disable the
``nova-placement`` service.
- The ``nova-placement`` api service will run as
its own ansible group ``nova_api_placement``.
- Nova cell_v2 support has been added. The default
cell is ``cell1`` which can be overridden by the
``nova_cell1_name``. Support for multiple cells
is not yet available.
