Add registry-1.docker.io to reverse proxy cache

To use the mirror, you'd create a /etc/docker/daemon.json file:

{
  "registry-mirrors": [
    "http://mirror.dfw.rax.openstack.org:8081/registry-1.docker/"
  ]
}

Obviously using your regional mirror.

We also use port 8081 because we need to ignore Expires headers, and
don't want to affect the rdo proxy.
