Description

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.
