The tests now pass. Signed-off-by: Ben Pope <[email protected]>
As of Redpanda v25.1, some consumer group metrics can be disabled by changing cluster config "enable_consumer_group_metrics". These are still enabled by default, but split them out into their own grouping. Signed-off-by: Ben Pope <[email protected]>

What does this PR do?
Motivation
Native consumer group lag metrics allows users to directly monitor lag in their consumer groups. This calculation is not possible within Datadog.
The new lag metrics are low cardinality, and do not have detail into which partitions are behind. That can be obtained by taking the group label from the metrics and running something like:
If that level of detail is sufficient, it's possible to remove the high cardinality metric
kafka.group_offset, which is what I've done in the default of v3.0.0.Review checklist
