 * Represents the metadata for a Google Cloud Storage HmacKeyResource.

 * HMAC keys allow applications to authenticate with Google Cloud Storage using
 * HMAC authentication. Applications can create a limited number of HMAC keys
 * associated with a service account. The application can use the HMAC keys to
 * authenticate with GCS. GCS will use the service account permissions to
 * determine if the request is authorized.
 *
 * @see https://cloud.google.com/storage/docs/authentication/hmackeys for
