The problem described to me in the kolla IRC channel was kolla polls
'nova service-list' until the computes show up, otherwise if the
computes aren't there when simple_cell_setup runs it will stop before it
creates the first (main) cell.

With this change in the API: https://review.openstack.org/#/c/442162/21

We iterate the cells to list services, so if you don't have the cell
created yet, you'll get nothing back.

The simple_cell_setup command is not great for a fresh install, since
it's not so simple it turns out. It works a bit easier for upgrades from
non-cells to cells but for a fresh install I wouldn't use it. I'd change
tooling for a fresh install to follow the steps in this document:

https://docs.openstack.org/developer/nova/cells.html#fresh-install

Title:
  empty nova service and hypervisor list

Status in kolla-ansible:
  New
Status in OpenStack Compute (nova):
  Invalid

Bug description:
  In current master, openstack compute service list and openstack hypervisor list (same issue with nova cli) result in an empty list.
  If I check the database, services are registered in the database.
