aiokafka 0.6.0 resolves a significant issue that has affected the stability of our Kafka consumers, namely that the UnknownMemberId exception as being raised, rather than aiokafka retrying.

• lsst-templatebot-aide
• ltd-events
• sqrbot-jr (it doesn't operate a consumer, but should be updated nonetheless)
• ook

If this ticket succeeds, we may not need to implement DM-23996 (an app to create a drumbeat Kafka topic that restarts consumers based on a "dead-man-switch" concept.
