KIP-4 — Metadata Protocol Changes

Accepted AdminProtocol

Introduces an AdminClient Java API backed by a wire protocol, providing programmatic operations for topic management, ACL management, and configuration changes without requiring direct ZooKeeper access. Prior to this, all administrative operations (kafka-topics.sh, kafka-acls.sh, etc.) wrote directly to ZooKeeper, coupling admin tooling to ZooKeeper connectivity and making multi-language admin clients impractical.
