Description
**Describe the problem**
We have seen in escalations where some server side rangefeeds are really slow due to slow clients, but they are holding the catch up scan semaphore. This can cause other server side rangefeeds to be blocked. We can consider adding some server side. If server side notices a client side rangefeed is slow, it should give up or ask clients to retry and not blocking all other rangefeeds.
