Re-instate transition jobs in staging
Re-instate transition jobs in staging

We seem to have ended up with transition jobs redirected in AWS staging
environment. Judging by the original commit message [1] these redirects
seem to have been intended for the Carrenza staging environment with the
jobs actually running in AWS staging.

As a whole bunch of time has passed I have no idea if these jobs will
actually succeed in staging or not.
