/**
 * Service Description: A service that handles tenant management, including CRUD and enumeration.
 *
 * 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:
 *
 * ```
 * $tenantServiceClient = new TenantServiceClient();
 * try {
 *     $formattedParent = $tenantServiceClient->projectName('[PROJECT]');
 *     $tenant = new Tenant();
 *     $response = $tenantServiceClient->createTenant($formattedParent, $tenant);
 * } finally {
 *     $tenantServiceClient->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.
 *
