KIP-78 — Cluster Id
Accepted Kafka 1.0 AdminBroker
Introduces a `clusterId` — a base64-encoded UUID stored in ZooKeeper at cluster initialization — exposed via the `ApiVersions` response and broker metadata. With multiple clusters becoming common, there is no reliable cluster-unique identifier for monitoring, auditing, or preventing a broker/client from accidentally connecting to the wrong cluster.
