[impv] Upload the resource to the special folder instead of the Root path

Now, we can upload files to the resource center, but if we cannot manage the path of the resource, there will make some errors. For example, different files have the same name.

I think we can upload the file to a special folder, such as `PYDS/workflow_name/workflow_version/task_name/task_version`.

But it will waste a lot of space storing the same files
