Fix potentially unlimited memory usage spike possible in raft.hup() which reads all unapplied committed entries in order to check that there are no unapplied config changes. This PR paginates this scan so that the spike is limited to MaxCommittedSizePerReady. It also terminates the scan early if a config change has been found. It is ported from etcd-io/raft#32. It is ported from tikv/raft-rs#530. Signed-off-by: tison <wander4096@gmail.com>
