Under high load, if there are many RaftGroup leaders on one machine and there
is a sudden crash, grpc may create many threads to handle requestVote and
appendEntry, etc.N, frequent thread creation and context switching, which may
lead to performance degradation.

It seems that grpc will not release the thread yet.
We can specify a fixed number of thread pools or periodically recycle threads
