 * Service Description: Manages App Engine applications.

 * 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:
 *
 * ```
 * $applicationsClient = new ApplicationsClient();
 * try {
 *     $operationResponse = $applicationsClient->createApplication();
 *     $operationResponse->pollUntilComplete();
 *     if ($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 = $applicationsClient->createApplication();
 *     $operationName = $operationResponse->getName();
 *     // ... do other work
 *     $newOperationResponse = $applicationsClient->resumeOperation($operationName, 'createApplication');
 *     while (!$newOperationResponse->isDone()) {
 *         // ... do other work
 *         $newOperationResponse->reload();
 *     }
 *     if ($newOperationResponse->operationSucceeded()) {
 *         $result = $newOperationResponse->getResult();
 *         // doSomethingWith($result)
 *     } else {
 *         $error = $newOperationResponse->getError();
 *         // handleError($error)
 *     }
 * } finally {
 *     $applicationsClient->close();
 * }
 * ```
 *
 * This service has a new (beta) implementation. See {@see
 * \Google\Cloud\AppEngine\V1\Client\ApplicationsClient} to use the new surface.

     *           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
