Bug Description

In https://review.opendev.org/c/openstack/tripleo-ansible/+/783703 idempotency was change to use dns_domain instead of a neutron tag with the hostname because of neutron's limit on 60 chars per tag.

The dns_domain is not set in Train, so after undercloud FFU running pre-provision commands to create the environment file describing the baremetal deployment end up creating new ports instead of updateing/re-using the existing ports that where created when deploying the Train overcloud.

We need to backport - https://review.opendev.org/c/openstack/tripleo-heat-templates/+/715883 from Victoria to train.

    Set dns_name propery on ports and networks

    Neutron's dns_assignments field includes a nice pice of
    structured data. This is a prerequirement for Designate
    usage. (No plan's to use that, but being a bit ready
    does'nt hurt.)

      {"hostname": "my-vm",
       "ip_address": "192.0.2.16",
       "fqdn": "my-vm.example.org."}

    Enable for the undercloud:
     - dns_domain_ports ml2 extension driver

    Need to backport this to train because network-v2 idempotency
    rely on the dns_doman. In Ie326f30fcc3d93533f4269cdfec40d3634684e22
    idempotency was change to use dns_domain instead of a neutron tag
    with the hostname because of neutron's limit on 60 chars per tag.

    Without this change the provisioning workflow will create duplicate
    ports when FFU upgrade is performed.

    Conflicts:
      overcloud.j2.yaml
