It may be this is partly a nova and partly a puppet-nova bug?  As it
seems the nova releasenotes and api_db sync help text is wrong, and it
seems like puppet-nova isn't driving the cells_v2 simple_cell_setup at
the appropriate time with the URL it expects (which isn't all that clear
as evidently it doesn't match the nova.conf setting with the same name).

Bug description:
  Trying to upgrade with recent trunk nova and puppet-nova gives this
  error:

  Notice: /Stage[main]/Nova::Db::Sync_api/Exec[nova-db-sync-api]/returns: error: Cell mappings are not created, but required for Ocata. Please run nova-manage db simple_cell_setup before continuing.
  Error: /usr/bin/nova-manage  api_db sync returned 1 instead of one of [0]
  Error: /Stage[main]/Nova::Db::Sync_api/Exec[nova-db-sync-api]/returns: change from notrun to 0 failed: /usr/bin/nova-manage  api_db sync returned 1 instead of one of [0]

  
  Debugging manually gives:

  $ sudo /usr/bin/nova-manage  api_db sync
  error: Cell mappings are not created, but required for Ocata. Please run nova-manage db simple_cell_setup before continuing.

  
  but...

  $ sudo nova-manage db simple_cell_setup
  usage: nova-manage db [-h]
                        
                        {archive_deleted_rows,null_instance_uuid_scan,online_data_migrations,sync,version}
                        ...
  nova-manage db: error: argument action: invalid choice: 'simple_cell_setup' (choose from 'archive_deleted_rows', 'null_instance_uuid_scan', 'online_data_migrations', 'sync', 'version')

  
  I tried adding openstack-nova* to the delorean-current whitelist, but with the latest nova packages there still appears to be this mismatch.
