> To support "bumpLeaderEpoch" RPC in the future, we should add a "leaderEpoch" field in PartitionChangeRecord, and move the leader epoch calculation logic from currently each node calculate the leader epoch when replying PartitionChangeRecord in PartitionRegistration class, to each time the PartitionChangeRecord creates, and each node only needs to take the leaderEpoch in the PartitionChangeRecord.
>  
> We should also consider the backward compatibility in this change.
