Yes but warnings:

* scenario005 is a 4nodes deployments in OpenStack Infra, it takes
quite a lot of CI resources.
* we would like to run the scenario which has OVN into
openstack/networking-ovn gate.

So I'm not sure this is really efficient. Scenario005 was created to
be run when touching pacemaker files in THT / puppet-tripleo and test
composable HA. Adding OVN to the stack is fine, but it also means the
job would run much more often (every time we patch OVN files in
TripleO and also for every patch in openstack/networking-ovn) - do we
really want that?
