Retire old rdu2 space.
    
    This space was in a networking cage thats going away and all the
    machines there are old and out of warentee.
    This space was intended for disaster recovery purposes.
    For that now we have a internal vm that can access our mirrored netapp
    storage, so we can sync anything off it we need to when iad2 is down.
    I will be resetting up a batcave13 in another datacenter to allow us a
    backup ansible/dns control host. bastion13/ns13/proxy13 will likely just
    go away forever. download-rdu01 should be replaced by the new
    download-cc-rdu01 once we have the new hardware in place for that.
