KIP-327 — Add describe all topics API to AdminClient
Discarded Admin
Proposes a dedicated `DescribeAllTopicsRequest` protocol RPC to atomically retrieve all topics' metadata in one call. Using `listTopics()` followed by `describeTopics(allNames)` sends a large `MetadataRequest` that returns redundant broker and cluster data, creating excessive network load in clusters with thousands of topics. (Discarded — addressed differently.)
