   *   The realm is specified by a particular module; the gid is as well, and
   *   is a module-defined id to define grant privileges. each grant_* field
   *   is a boolean value.

   *   (optional) If provided, read/write grants for that realm only. Defaults
   *   to NULL.
   * @param bool $delete
   *   (optional) If false, does not delete records. This is only for
   *   optimization purposes, and assumes the caller has already performed a
   *   mass delete of some form. Defaults to TRUE.
