示例1: UpdateCluster
// UpdateCluster updates a Cluster referenced by ClusterID with the given ClusterSpec.
// - Returns `NotFound` if the Cluster is not found.
// - Returns `InvalidArgument` if the ClusterSpec is malformed.
// - Returns `Unimplemented` if the ClusterSpec references unimplemented features.
// - Returns an error if the update fails.
