KIP-560 — Auto infer external topic partitions in stream reset tool

Discussion StreamsAdmin

Adds an `--all-user-topics` flag to the Kafka Streams application reset tool to automatically discover and reset offsets for all externally committed topic offsets without requiring the user to explicitly list input topic names. Currently, operators must manually enumerate all external input topics and pass them to the reset tool, which is error-prone and cumbersome for applications with many input topics.
