[ZOOKEEPER-1818] Correctly handle potential inconsistent zxid/electionEpoch
and peerEpoch during leader election
This is similar to the 3.4 implementation in Jira ZOOKEEPER-1817, main
differences with that:
1. removed bcVote, in Vote.equals it will skip compare peerEpoch when one
of the version is 0x0.
2. added detailed scenarios which we tried to solve with peerEpoch update
and the change in Vote.equals.
3. removed ooePredicate with inlined one, since master code is tracking
voteSet..
4. improved the tests to make it cleaner.
