revlog: skip opener options to pass candidate_group_chunk_size value We can directly set the option in the config object now.

revlog: skip opener option to pass delta_both_parents value We can directly set the option in the config object now.

revlog: skip opener option to pass chunk_cache_size value We can directly set the option in the config object now.
