    Use deploy_changes for sets of nodes

    The deploy_changes method involves additional nodes into deployment to
    perform necessary tasks to keep clustered software in a consistent
    state. A direct execution of tasks on a specific set of nodes does not
    involve other necessary nodes and it leads to some failures during
    deployments.
