I removed one of my computes (compute02) from cluster (removed its nova and neutron agnts and also removed it from inventory). 

On compute02:  I 1) removed br-provider and br-int ,  2) removed ovn-* packages 3) rm -r /openstack/venvs

Then, I removed `compute02` from `network-gateway_hosts` in `openstack_user_variable.yaml`. Afterwards, I re-added this node as a new compute to my OSA.

When I ran the last step of the installation (`sudo openstack-ansible setup-openstack.yml --limit localhost,compute02,nova_all`) compute02 added again as a gw chassis to my cluster, in `TASK [os_neutron : Configure ovn-controller]`! It seems the node is defined as a neutron-ovn-controller . Where the hosts belong to `ovn_controller` group are defined?
