Review Comment:
We have a `notifyLeaderChanged(..)` method in `EventApi`. So, both the
Leader and the Followers will get this event. Of course, the server could
check if it becomes the leader by checking the `newLeaderId` parameter.
This method `LeaderEventApi.notifyLeaderReady()` is in `LeaderEventApi`.
So, only the Leader will get this event. The name looks good to me. Also, the
javadoc is clear.
```java
/**
* Notify the {@link StateMachine} that this server becomes ready after
changed to leader.
*/
default void notifyLeaderReady() {}
```
