wsme and pecan are now in devstack so we are running with their
git trees in the rest of the gate. We need to quickly put the
symetric gate on their side as well, to ensure that they can't
break us with a git commit that doesn't work on the rest of
OpenStack.
The job definitions are based on what we require of oslo.config
and oslo.messaging.
