Sorry to keep changing this. I hope these are the last few changes. The
spout should now seek to the lowest retriable offset for each partition when
retrying tuples, instead of seeking back to the last committed offset. This
means there's not as far as I can see any reason to worry about maxPollRecords
being set too low compared to maxUncommittedOffsets, so I've reverted that part
of KafkaSpoutConfig.
