The allowEmptyFolder option is no longer functional because:
1. The code that used it was already commented out
2. Empty folder cleanup is now handled asynchronously by EmptyFolderCleaner
The CLI flags are kept for backward compatibility but marked as deprecated
and ignored. This removes:
- S3ApiServerOption.AllowEmptyFolder field
- The actual usage in s3api_object_handlers_list.go
- Helm chart values and template references
- References in test Makefiles and docker-compose files
