How to use the @google-cloud/common.Operation function in @google-cloud/common

* // Be sure to register an error handler as well to catch any issues which
 * // impeded the operation.
 * //-
 * operation.on('error', function(err) {
 *   // An error occurred during the operation.
 * });
 *
 * //-
 * // To force the Operation object to stop polling for updates, simply remove
 * // any "complete" listeners you've registered.
 * //
 * // The easiest way to do this is with `removeAllListeners()`.
 * //-
 * operation.removeAllListeners();
