KIP-927 — Improve the kafka-metadata-quorum output

Accepted Kafka 3.6 KRaftAdmin

Adds a `--human-readable` flag to the `kafka-metadata-quorum` CLI tool that converts `LastFetchTimestamp` and `LastCaughtUpTimestamp` fields from Unix epoch milliseconds to human-readable relative delay strings (e.g., `366 ms ago`). Raw epoch timestamps in the quorum replication status output require manual conversion to assess voter lag.
