 * Service Description: A service for running workflows, such as pipelines consisting of Docker
 * containers.
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods. Sample code to get started:
 *
 * ```
 * $workflowsServiceV2BetaClient = new WorkflowsServiceV2BetaClient();
 * try {
 *     $pipeline = new Pipeline();
 *     $operationResponse = $workflowsServiceV2BetaClient->runPipeline($pipeline);
 *     $operationResponse->pollUntilComplete();
 *     if ($operationResponse->operationSucceeded()) {
 *         $result = $operationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $operationResponse->getError();
 *         // handleError($error)
 *     }
 *     // Alternatively:
 *     // start the operation, keep the operation name, and resume later
 *     $operationResponse = $workflowsServiceV2BetaClient->runPipeline($pipeline);
 *     $operationName = $operationResponse->getName();
 *     // ... do other work
 *     $newOperationResponse = $workflowsServiceV2BetaClient->resumeOperation($operationName, 'runPipeline');
 *     while (!$newOperationResponse->isDone()) {
 *         // ... do other work
 *         $newOperationResponse->reload();
 *     }
 *     if ($newOperationResponse->operationSucceeded()) {
 *         $result = $newOperationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $newOperationResponse->getError();
 *         // handleError($error)
 *     }
 * } finally {

     *     @type string $apiEndpoint
     *           The address of the API remote host. May optionally include the port, formatted

     *     @type string|array|FetchAuthTokenInterface|CredentialsWrapper $credentials
     *           The credentials to be used by the client to authorize API calls. This option
     *           accepts either a path to a credentials file, or a decoded credentials file as a
     *           PHP array.
     *           *Advanced usage*: In addition, this option can also accept a pre-constructed
     *           {@see \Google\Auth\FetchAuthTokenInterface} object or

     *           Client method configuration, including retry settings. This option can be either
