I think we should prioritize mirroring the GIT (not gerrit) repos to PHX,
this will help:

   1. Speed up all post merge jobs and reduce potential of errors from git
   clone (they will be in the same network)
   2. Reduce load (?) from the gerrit server and perhaps reduce errors of
   the per patch jobs that will still run from gerrit.ovirt.org (AMAZON)
   3. A longer goal will be either to migrate the gerrit server to PHX or
   to find away to properly mirror the gerrit server (but then i fear there
   might be race/problem as mentioned)


We have an open ticket on that which was blocked due to not wanting to
clone any private git repos as well, we need to look into that again.
