   @cmccabe, here's the new metadata summary format:
   
   
   > [2023-02-02 11:21:52,175] TRACE Sending RPCs to broker before moving to dual-write mode. Metadata at offset 122 and epoch 1 includes 3 brokers (0 changed), 3 topics (0 changed), 0 features (0 changed), 10 configs (0 changed), 1 producer id (0 changed) (org.apache.kafka.metadata.migration.KRaftMigrationDriver:461)
   
   The migration manifest format is the same as before:
   
   > [2023-02-02 11:38:01,569] INFO Completed migration of metadata from ZooKeeper to KRaft. 71 records were generated in 342 ms across 4 batches.
