### Synopsis
Perform a rolling update of the given ReplicationController.
Replaces the specified replication controller with a new replication controller by updating one pod at a time to use the
new PodTemplate. The new-controller.json must specify the same namespace as the
existing replication controller and overwrite at least one (common) label in its replicaSelector.
