The fqdn format will not work on openshift deployments since the IngressDomain is only required for Kubernetes deployment and it can be empty. If a registry is successfully deployed it should update the URL in cr.Status.URL field so we can rely on that setting as long as it's not empty.

Blocked, needs rebasing to changes in #30 and #31.
