Base on the current implementation, the leader start up and treat every txns in
its txnlog as committed. It add those txn into committedLog and the follower
get proposal/commit packet pair for those txns as part of the sync-up. Let me
know what you think, this problem is quite complicate if we don't want to break
compatibility.

agree.
We have some discussions in ZOOKEEPER-1549. I think it is quite complicate even
if we don't consider the compatibility.
