      Description

      Ideas

      • 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
