The listener.Cleanup method will be called during executor.Shutdown and route.restart, so it should serve all kinds of listeners rather than a single tun device. Currently listener.ReCreateTun will call it to handle some internal affairs, This should be decoupled. In this way, the cleanup tasks for data outside the process life cycle that other listeners will add here in the future will not be accidentally triggered by configuring tun.
