Add nova-api database setup for Mitaka

Mitaka requires the use of a separate nova-api database;
ensure that this is setup on the shared-db relation and add
a new [api_database] section to the mitaka nova.conf file.

Add a new NovaAPISharedDBContext wrapper to prefix the key
names for the nova-api database with 'nova_api_' so that we
can present two database connections to the same configuration
file.

Ensure that 'nova-manage api_db sync' is called for database
setup for >= mitaka release.

For upgrades, ensure that the database migration and service
start is deferred until the nova_api database has been
setup by the related mysql service.
