Review Comment:
thanks, if it is the case that batch copy and batch delete is not actually
used, I would suggest make them just call gcsio.copy and gcsio.delete one by
one at this moment, to avoid functioning regression. and leave performance
regression (use actual batch) as near follow up. At the same time file a
Feature Request to gcs client that make a batch that can return all request
reaults.
