KIP-268 — Simplify Kafka Streams Rebalance Metadata Upgrade

Accepted Kafka 2.0 StreamsConsumer

Redesigns the Kafka Streams rebalance metadata versioning scheme to support rolling upgrades between metadata versions without requiring full application shutdowns, enabling single rolling bounce upgrades. The original metadata upgrade mechanism (used in 0.10.1.0) required the entire application to be stopped before upgrading, because mixed-version clusters would fail to interpret newer metadata formats.
