Deploy a small cloud. Add one host to the compute group in the
inventory, and scale out:
$ kolla-ansible deploy --limit <new compute host>
The command succeeds, but creating an instance fails with the following:
Host 'compute0' is not mapped to any cell
This happens because we only discover computes on the first host in the
cell's nova conductor group. If that host is not in the specified limit,
the discovery will not happen.
This change fixes the issue by running compute discovery when any ironic
or virtualised compute hosts are in the play batch, and delegating it to
a conductor.
