kv.BypassLatch was introduced to handle the fake transaction confliction problem in the old implementation. After redesign of the latch scheduler, it's not needed any more. Enable latch scheduler makes CI to run it, we can fix bugs and make this feature more stable. There is a small performance penalty, less than 5%, users are free to disable it.
