Create $::rdo_mirror_host

Currently, openstack-infra has create an proxy cache of
trunk.rdoproject.org. This is a short term solutions until we add RDO
to our AFS mirrors. Update repo.pp to start using it.

We also use the direct hash from delorean.repo, to avoid potential
issue where packages chages on remote node after we start downloading
things.
