Andrew Schofield updated KAFKA-20858:
-------------------------------------
Description:
The SubscriptionState class in the client is a core class in the consumer and
share consumer. It keeps track of all manner of consumer state such as
subscribed topics, assigned partitions and fetch positions.
Although there are some concepts which are common to consumer group and share
group subscription state management, there are also many differences.
This task refactors the subscription state to remove this false coupling
between group types, and give share groups better control over the topics
included in the metadata.
