    This task starts a WebSocket server.

    It's a thin wrapper around the event loop's ``start_serving`` method.

    `ws_handler` is the WebSocket handler. It must be a coroutine accepting
    two arguments: a :class:`~websockets.framing.WebSocketServerProtocol` and
    the request URI. The `host` and `port` arguments and other keyword
    arguments are passed to ``start_serving``. The return value is a list of
    objects that can be passed to ``stop_serving``.

    Whenever a client connects, the server accepts the connection, creates a
    :class:`~websockets.framing.WebSocketServerProtocol`, performs the opening
    handshake, and delegates to the WebSocket handler. Once the handler
    completes, the server performs the closing handshake and closes the
    connection.
