Instead of using a mirror, the CI registry is now pupulated with
container images that get pulled and tagged as if they get from Docker
Hub or other locations.
This is more of a manual mirror, as the Docker Registry mirror
functionality is not flexible enough for our usecase (push images
without providing them on docker.io).

This makes it possible to pull images from Docker Hub through the local
container image registry in the CI OpenShift deployment. The registry in
the CI is configured with the 'cephcsibot' account so that pulling
images is accounted towards the account, and not anonymous consumers
within the whole CentOS CI.
There should be no need to manually sync the images between the local
registry and Docker Hub anymore.

With a private container image registry, the images that CI jobs use can
be cached and re-used. This speeds up the CI jobs, as building the
container images takes up the majority of the runtime for some jobs.
