    Add standard attributes to segment resource

    Standard attributes (i.e. revision_number, created_at, updated_at)
    are missing in the segment resource. This is because the controller
    doesn't process extensions on rendering the response. This patch
    fixes it. In particular, this patch does the following:
    * Process extensions when making the segment dict. This allows
      other extensions to add attributes to segment response.
    * Make segment extension implement update_attributes_map.
