  - 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.
