* https://review.opendev.org/c/openstack/tripleo-heat-templates/+/821797
* Current issue - tempest failure
* Check if its possible to use ipv4 private network on IPV6 tenant network?
* if not, Is it possible in tempest to create IPV6 network instead of IPv4 network

### Move ctlplane to IPV6

* Changes required in ovb-manage role to allow creation of ipv6 network
* Add a variable for ipv6 in pre-ovb-create.yaml
* https://github.com/rdo-infra/review.rdoproject.org-config/blob/master/playbooks/tripleo-rdo-base/pre-ovb-create.yaml
* Modify undercloud.conf template / pass details via featureset to create correct ipv6 ctlplane
