KIP-590 — Redirect Zookeeper Mutation Protocols to The Controller

Accepted Kafka 2.7 KRaftProtocol

Routes all ZooKeeper mutation RPCs (AlterConfig, CreateAcls, DeleteAcls, AlterPartitionReassignments, etc.) exclusively through the controller during the KIP-500 bridge release. This ensures no broker writes directly to ZooKeeper, making the controller the single writer and enabling safe migration to KRaft.
