Deploying RHOSO beta on OCP 4.14.30 (dual stack cluster). After applying the OpenStackControlPlane CR, the memcached pod failed to start. Pod log shows the following error:

Invalid IPV6 address: "[10.131.0.91"failed to listen on TCP port 11212: Success

While the OCP cluster, is dual stack, the OpenStack configuration is being built with only IPv4 addresses.
