KIP-800 — Add reason to JoinGroupRequest and LeaveGroupRequest

Accepted Kafka 3.2 Consumer

Adds an optional `Reason` string field to `JoinGroupRequest` and `LeaveGroupRequest` so the broker can log why a consumer joined or left the group. Broker-side rebalance troubleshooting was hampered by the absence of a human-readable reason in these requests, since only the client side logged the reason.
