/**
 * Service Description: Cloud OS Login API.
 *
 * The Cloud OS Login API allows you to manage users and their associated SSH
 * public keys for logging into virtual machines on Google Cloud Platform.
 *
 * 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:
 *
 * ```
 * $osLoginServiceClient = new OsLoginServiceClient();
 * try {
 *     $formattedName = $osLoginServiceClient->posixAccountName('[USER]', '[PROJECT]');
 *     $osLoginServiceClient->deletePosixAccount($formattedName);
 * } finally {
 *     $osLoginServiceClient->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.
