  - Use external_ip to populate the node address

    Use the new external_ip inventory variable to populate node address.
    Note that cluster_ip is still used if external_ip has not been set.
    This makes it possible to connect to kubernetes apiserver using the external_ip
    without disabling ssl cert verification.
    As an added bonus, the inventory hostname is now used as the node name to make
    node names more predictable.

  - Add external_ip variable

    Adds the external_ip variable that can be used to set ip different
    from cluster_ip, like public/floating/elastic ip, that can be used to externally
    communicate with kubernetes nodes. Mainly useful
    for the control plane and communication with
    api server.
