Review comment:
       Okay. Thanks for your patience in convincing me.
   
   Then, 1) Making the default internal topic names (e.g., 
`DistributedConfig.OFFSET_STORAGE_TOPIC_CONFIG`) in the standalone mode 
consistent 2) Provide a way to migrate internal topics are beyond the scope of 
this issue, and it should be filed as a separate KIP. Right?
