Review Comment:
   I think it would be better to have the `wrapZkException` blocks inside 
`migrateTopics`, `migrateBrokerConfigs`, `migrateClientQuotas`, 
`migrateProducerId`. Then we can have a simple mental rule like: if you do 
something with zkClient, you need to wrap it. And not have to analyze control 
flow.
