code: def _custom_response_edit(self, method, url, headers, body, response):
          
          if self.get_implementation().is_mock():
              delay = self.get_setting("MOCKDATA_DELAY", 0.0)
              time.sleep(delay)

docs: This method allows a service to edit a response.
  
          If you want to do this, you probably really want to use
          _edit_mock_response - this method will operate on Live resources.
