k8s: Allow Dublin cluster creation using RKE

This patch adds sample cluster.yml which is based on Dublin cluster
configuration file [1]. Main difference is in avoiding repetition by
using anchors and alias nodes.

Actual cluster creation provisioner is disabled by default because
'control' and 'worker' nodes might not be ready yet.
