Comment # 2 on bug 1103906 from Richard Brown

- the removal of current admin/worker/plain system roles - DONE
- focus on kubeadm as the default k8s bootstrapping tool (including a new
system role) - DONE
- adaption & introduction of new openQA tests to fit this new architecture  -
DONE (though Multi-machine tests still WIP)
- removal of Container RPMs from Factory & Kubic media - DONE

There was no major fallout, users are able to use this new architecture, so
this bug is being closed
