(defaults to 100).

        ssl can be set to an SSLContext to enable SSL over the
        accepted connections.

        reuse_address tells the kernel to reuse a local socket in
        TIME_WAIT state, without waiting for its natural timeout to
        expire. If not specified will automatically be set to True on
        UNIX.

        reuse_port tells the kernel to allow this endpoint to be bound to
        the same port as other existing endpoints are bound to, so long as
        they all set this flag when being created. This option is not
        supported on Windows.

        ssl_handshake_timeout is the time in seconds that an SSL server
        will wait for completion of the SSL handshake before aborting the
        connection. Default is 60s.

        start_serving set to True (default) causes the created server
        to start accepting connections immediately.  When set to False,
        the user should await Server.start_serving() or Server.serve_forever()
        to make the server to start accepting connections.
