        Indicate that we will stop performing the given option.

        Returns a Deferred that fires with True when the peer acknowledges
        we have stopped performing this option.  If the option is already
        disabled locally, the Deferred will fail with L{AlreadyDisabled}.
        If negotiation regarding this option is already in progress,

        Note: It is currently possible that this Deferred will never fire,
        if the peer never responds, or if the peer believes the option to
        already be disabled.
