> In KAFKA-5396, we saw that the consumers which verify the data in multiple topics could read the same offsets multiple times, for instance when a rebalance happens. 
> This would detect spurious duplicates, causing the test to fail. We should dedup the consumed messages by offset and only fail the test if we have duplicate values for a if for a unique set of offsets.
