   Yes, I think we should disable this by default. Option can be in catalog option.

   Currently the implementation __always__ fetches metadata when retrieving file statuses, this could slow down the operation of normal tables since the metadata is only used by object tables.
   
   I'm thinking adding `FileIO#enableFeature(String)`, `FileIO#disableFeature(String)` to allow on-the-fly tuning of FileIO behaviors. What's your opinions?
