In order to add another compute node to an existing DevStack setup
(multi-node) we need to set a few extra variables to the local.conf to
enable the OVN driver in neutron.
The patch is also adding a new neutron_plugin_create_nova_conf function
to the ovn_agent module (no-op) otherwise the DevStack setup will fail.
