> ReplicaFetcherThread's handlePartitionsWithErrors() function needs to be implemented (currently it is an empty function) such that upon getting errors on these partitions, the fetcher thread will back off the corresponding simple consumer to retry fetching that partition.
> This can happen when there is leader migration, the replica may get a bit delayed receiving the leader ISR update request before keeping retry fetching the old leader.
