[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

The issue names no files, tests, or entry points. Locate the resource-center upload path and the workflow/task metadata used to construct resource paths, then clarify how duplicate files should be deduplicated and how existing uploads should be handled. Done means uploads no longer collide at the Root path without wasting space on identical files.
