VRE-520 Add object-storage-download
- Reenable old KDP workflow
- Make it work with OIDC
- Rename all to kdp workflow for now, so we can change it easily to the name we want.
- Update the example and have an S3 bucket and S3 prefix instead of the previous options.
- Update the backup script so it can deal with nested folders when we give it a folder as for the source and for the url in same tree structure internally (update the tests of the backupscript to have it work with that).
- Update the images that used the backupscript cuz depending on the environment something needs to change.
