KIP-1222 — Acquisition lock timeout renewal in share consumer explicit mode
Accepted Kafka 4.2 Consumer
Adds a lock renewal RPC for share consumers in explicit acknowledgement mode so that a consumer processing a long-running record can extend its acquisition lock timeout without changing the record's delivery state. Without renewal, a record under active processing would have its acquisition lock expire and become re-deliverable to another consumer if processing exceeded the lock timeout.
