OpenShift Route backend

[nightkr]

OpenShift provides the Route CRD, which allows OpenShift to automatically allocate public hostnames for services and provides load balancing and a convention for DNS configuration.

We could integrate by:

1. Creating a serviceType that creates Route objects
2. Setting the Listener's addresses to Route.status.ingress[].host, but only if ingress[].conditions[type=Admitted].status=True (to prevent impersonation attempts)
