patch used was

- Change haproxy from ctlplane to internal_api.
   I found the template /usr/share/openstack-tripleo-heat-templates/puppet/all-nodes-config.yaml defines the ctlplane. I changed the variables:
   controller_virtual_ip: {get_param: [NetVipMap, ctlplane]} to controller_virtual_ip: {get_param: [NetVipMap, internal_api]}
   tripleo::haproxy::controller_virtual_ip: {get_param: [NetVipMap, ctlplane]} to internal_api
   tripleo::keepalived::controller_virtual_ip: {get_param: [NetVipMap, ctlplane]} to internal_api
   tripleo::redis_notification::haproxy_monitor_ip: {get_param: [NetVipMap, ctlplane]} to internal_api  


Can this be somehow enabled on Director level and consider it supported?

Thanks
