Jason Gustafson resolved KAFKA-7150.
------------------------------------
    Resolution: Not A Problem

This is no longer a problem since we have removed the logic to raise a fatal error from the out of range error handling.

> If the followers fails to process data for one topic partitions, like out of order offsets error, the whole ReplicaFetcherThread is killed, which also stops fetching for other topic partitions serviced by this fetcher thread. This may result in un-necessary under-replicated partitions. I think it would be better to continue fetching for other topic partitions, and just remove the partition with an error from the responsibility of the fetcher thread.
