We very rarely do backports in RDO repos so I think we can safely remove
the mirrors from upstream projects from review.r.o.

However my understanding is that we still may need it in exceptional cases.
For those cases we may create the patches repos and branches when required
and use the existing workflow based on patches to review.r.o and rdopkg.
Otherwise, we need to investigate a new workflow. Am I right?
