> In Ratis, 2 types of log entries exists, it can either of type StateMachineLogEntryProto or RaftConfigurationProto. Only StateMachineLogEntryProto is processed by the state machine, however RaftConfigurationProto is processed internally. In certain cases, state machine might like to maintain the sequence of events being processed by it i.e. ContainerStateMachine for Ozone. In such cases State machine should be notified of index updates while processing RaftConfigurationProto.

>     RaftConfigurationProto configurationEntry = 4;
