KIP-1162 — Redesign ClientQuotaCallback#updateClusterMetadata

Discarded AdminSecurity

Deprecates ClientQuotaCallback#updateClusterMetadata(Cluster) and introduces a new ClientQuotaCallbackHandler interface with an updateClusterMetadata(ClusterMetadata) method that passes a minimal, efficiently updated metadata object. The existing method received a full immutable Cluster object recreated on every metadata change, causing excessive memory pressure on large clusters, and carried misleading controller/listener semantics in KRaft mode.
