KIP-605 — Expand Connect Worker Internal Topic Settings

Accepted Kafka 2.6 Connect

Exposes additional topic-level configuration properties (e.g., `cleanup.policy`, `min.insync.replicas`, `retention.ms`, compression type) for each of the three Connect internal topics (`config.storage.topic`, `offset.storage.topic`, `status.storage.topic`) so workers can create them with the correct settings. Previously only `replication.factor` and `partitions` were configurable, leading to internal topics being created with broker defaults that were often inappropriate for Connect's durability and compaction requirements.
