Title:
  os_nova might create a duplicate cell1

Status in OpenStack Compute (nova):
  New
Status in openstack-ansible:
  Fix Released

Bug description:
  The "Perform cell_v2 initial cell setup" task runs "nova-manage
  cell_v2 create_cell" with endpoints for the DB and RabbitMQ. This is
  idempotent on the Nova side as long as you give exactly the same
  endpoints. If you don't, then Nova creates a new, almost identical,
  cell.

  Experienced this issue when adding a RabbitMQ node to the cluster, I
  ended up with two "cell1". This confuses Nova a little bit...
  "openstack compute service list" returns every service twice, resource
  usage reports are incorrect by a factor of two, etc.

  Because (as far as I know) OSA can handle only one cell anyway
  currently, it should *update* the existing cell if there is one,
  instead of creating it.
