docs: :param bool spawn_on_request: Spawn workers only after the first request.
  
          :param Algo cheaper_algo: The algorithm object to be used used for adaptive process spawning.
              Default: ``spare``. See ``.algorithms``.
  
          :param int workers_min: Minimal workers count. Enables cheaper mode (adaptive process spawning).
  
              .. note:: Must be lower than max workers count.
  
          :param int workers_startup: The number of workers to be started when starting the application.
              After the app is started the algorithm can stop or start workers if needed.
  
          :param int workers_step: Number of additional processes to spawn at a time if they are needed,
