    """Class used to control a list of watchers.

    Options:

    - **watchers** -- a list of Watcher objects
    - **endpoint** -- the controller ZMQ endpoint
    - **pubsub_endpoint** -- the pubsub endpoint
    - **statsd** -- If True, a circusd-stats process is run (default: False)
    - **stats_endpoint** -- the stats endpoint.
    - **statsd_close_outputs** -- if True sends the circusd-stats stdout/stderr
      to /dev/null (default: False)
    - **multicast_endpoint** -- the multicast endpoint for circusd cluster
      auto-discovery (default: udp://237.219.251.97:12027)
      Multicast addr should be between 224.0.0.0 to 239.255.255.255 and the
      same for the all cluster.
    - **check_delay** -- the delay between two controller points
      (default: 1 s)
    - **prereload_fn** -- callable that will be executed on each reload
      (default: None)
    - **context** -- if provided, the zmq context to reuse.
      (default: None)
    - **loop**: if provided, a :class:`zmq.eventloop.ioloop.IOLoop` instance
       to reuse. (default: None)
    - **plugins** -- a list of plugins. Each item is a mapping with:

        - **use** -- Fully qualified name that points to the plugin class
        - every other value is passed to the plugin in the **config** option
    - **sockets** -- a mapping of sockets. Each key is the socket name,
      and each value a :class:`CircusSocket` class. (default: None)
    - **warmup_delay** -- a delay in seconds between two watchers startup.
      (default: 0)
    - **httpd** -- If True, a circushttpd process is run (default: False)
    - **httpd_host** -- the circushttpd host (default: localhost)
    - **httpd_port** -- the circushttpd port (default: 8080)
    - **httpd_close_outputs** -- if True, sends circushttpd stdout/stderr
      to /dev/null. (default: False)
    - **debug** -- if True, adds a lot of debug info in the stdout (default:
      False)
    - **debug_gc** -- if True, does gc.set_debug(gc.DEBUG_LEAK) (default:
      False)
      to circusd to analyze problems (default: False)
    - **proc_name** -- the arbiter process name
    - **fqdn_prefix** -- a prefix for the unique identifier of the circus
                         instance on the cluster.
    - **endpoint_owner** -- unix user to chown the endpoint to if using ipc.
