Controls what metadata fields are included in the response.
For those operations that return the metadata of an Object or Bucket, this option controls if all the fields are returned (using full) or if the ACL fields (which can be long) are to be excluded (using noACL).
Use the Fields option for more fine-grained control over the returned fields.
