The upgrade to mitaka requires the creation of the new database nova_api.

For the blanket upgrade approach db_joined is called after the upgrade to guarantee the creation of the DB:
https://github.com/openstack/charm-nova-cloud-controller/blob/master/hooks/nova_cc_hooks.py#L257

But when using action managed upgrades, config_changed is called but db_joined is not:
https://github.com/openstack/charm-nova-cloud-controller/blob/master/actions/openstack_upgrade.py#L48

This fails to create the required new db.
