- Remove Galera related code from lock0lock.cc and lock0wait.cc especially case when we crash on BF-BF conflict.
- We need only way to "kill" transactions
- Galera provider should order (total order) between BFs before they take row locks
- We let BF wait for other BF if necessary
- If there is lock wait timeout ==> retry
- If there is deadlock ==> retry
- If there is failure enough times in retry start inconsistency voting
