Description
Today when a TwillRunnable is restarted, the call sends a stop message to the TwillRunnable, and then starts new TwillRunnable without waiting for the stopping runnable to finish stopping.
This can leave a non-responding TwillRunnable container running, and can lead to issues like two TwillRunnables with same instance id running at the same time.
We should kill the containers that don't respond to stop message.
