Review comment:
Looks like we need to call computeAndUpdateLastAppliedIndex. As
applyLogToStateMachine in StateMachineUpdater when configEntry, we call
stateMachine.event().notifyConfigurationChanged(next.getTerm(),
next.getIndex(), next.getConfigurationEntry());
As in OM StateMachine, we update lastAppliedIndex using
computeAndUpdateLastAppliedIndex.
