> This Jira proposes to add support for notifying the state machine whenever 
> the server state changes.
> This would help the state machine to immediately discover whenever there is a 
> state change on its server.
> If a state machine implementation can service read requests without logging 
> to the Server, this notification would help prevent an old leader from 
> servicing any new requests.
> Whenever there is a state change on the server, it should notify its state 
> machine of this change.
