> The API is designed for scheduling SCPs for dead servers after we loss all the proc wals, but in TestHbck we use hbck to schedule a SCP for a live server. In order to pass the test, we need to move it from online servers to dead servers otherwise we may retain the assignment on the 'dead' server and cause the UT hang. And it is no harm if the server is not online when we call this method, so it is fine.
