KIP-550 — Mechanism to Delete Stray Partitions on Broker

Discussion Broker

Introduces a mechanism for brokers to detect and clean up stray partitions — log directories present on disk but unknown to the controller — that accumulate when partition reassignment completes while the original broker is offline. Stray partitions waste disk space, can cause log directory scanning overhead, and are invisible to operators with no automated cleanup path.
