Comment 9 for bug 1824579

<< I think I see the issue here. Its because I swapped out a hiera data lookup in t-h-t for OVNSouthboundServerPort in that commit. Let me see if I can post a fix here shortly.

Not sure if ^^ is the actual issue considering only tls(fs039) job is affected. I mean if this(String/Integer) is the cause why only tls job affected?
The issue i think is the change https://review.openstack.org/#/c/639119/16/deployment/ovn/ovn-metadata-container-puppet.yaml@284, looking at code it seems it looks for .type at when metadata_settings is not null(currently {}) http://git.openstack.org/cgit/openstack/tripleo-heat-templates/tree/extraconfig/nova_metadata/krb-service-principals.j2.yaml#n68, i can fire up a patch to confirm this meanwhile.
