/**
 * Service Description: Service for creating, configuring, and deleting Cloud Bigtable Instances and
 * Clusters. Provides access to the Instance and Cluster schemas only, not the
 * tables' metadata or data stored in those tables.
 *
 * 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:
 *
 * ```
 * $bigtableInstanceAdminClient = new Google\Cloud\Bigtable\Admin\V2\BigtableInstanceAdminClient();
 * try {
 *     $formattedParent = $bigtableInstanceAdminClient->projectName('[PROJECT]');
 *     $instanceId = '';
 *     $instance = new Google\Cloud\Bigtable\Admin\V2\Instance();
 *     $clusters = [];
 *     $operationResponse = $bigtableInstanceAdminClient->createInstance($formattedParent, $instanceId, $instance, $clusters);
 *     $operationResponse->pollUntilComplete();
 *     if ($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 = $bigtableInstanceAdminClient->createInstance($formattedParent, $instanceId, $instance, $clusters);
 *     $operationName = $operationResponse->getName();
 *     // ... do other work
 *     $newOperationResponse = $bigtableInstanceAdminClient->resumeOperation($operationName, 'createInstance');
 *     while (!$newOperationResponse->isDone()) {
 *         // ... do other work
 *         $newOperationResponse->reload();
 *     }
 *     if ($newOperationResponse->operationSucceeded()) {
 *       $result = $newOperationResponse->getResult();
 *       // doSomethingWith($result)
 *     } else {
 *       $error = $newOperationResponse->getError();
 *       // handleError($error)
 *     }
 * } finally {
 *     $bigtableInstanceAdminClient->close();
 * }
 * ```
 *
 * Many parameters require resource names to be formatted in a particular way. To assist
 * with these names, this class includes a format method for each type of name, and additionally
 * a parseName method to extract the individual identifiers contained within formatted names
 * that are returned by the API.
