Replica fetcher thread does not implement any back-off behavior

      The current replica fetcher thread will retry in a tight loop if any error occurs during the fetch call. For example, we've seen cases where the fetch continuously throws a connection refused exception leading to several replica fetcher threads that spin in a pretty tight loop.

      To a much lesser degree this is also an issue in the consumer fetcher thread, although the fact that erroring partitions are removed so a leader can be re-discovered helps some.
