    Modify the number of nodes in a cluster in a private cloud.

    Modifying a cluster is a long-running operation and it may take over an hour.

        zone: zone in which your private cloud is located.
        private_cloud_name: name of the private cloud hosting the cluster.
        cluster_name: name of the cluster.

        An Operation object related to cluster modification operation.
