Fix typo in ovn-dbs-cluster northd kolla config file
Fix typo in ovn-dbs-cluster northd kolla config file

The correct variable name in tripleo-ansible/roles/tripleo_ovn_cluster/templates/ovn_cluster.j2
is OVN_NORTHD_OPTS. With this change we see that the ovn_northd process
starts correctly with all the right parameters:

    root      104187  0.0  0.0  43056  8868 ?        S    16:57   0:00
