I am currently +1 on the creating different kolla-kubernetes/kolla-k8s
repo and reevaluating the merge/split thing once we have a stable
kubernetes deployment with the minimum deployment features added.
Perhaps this list can be maintained somewhere in documentation and
updated as we move along.
I think from the lessons we have learnt during kolla-mesos regarding
the participation and ABI, we need to ensure that we do not get into
the similar situation with kolla-kubernetes and maintain consistency.
