text: Title: django-storages, boto3, and django-progressbarupload
  Body: I'm building a small app that stores whalesong. I've got my forms uploading to an S3 via boto3 and django-storages. I've also installed the development version of django-progressbarupload and am running django 2.0.6
  
  django-progressbarupload gets it's progress data via
  ```
        $.getJSON(upload_progress_url, {'X-Progress-ID': uuid}, function(data, status){
  ```
  upload_progress_url is 'progressbarupload/upload_progress'. but the progress data just returns success / the full file size right away, even though the file is still uploading to S3. I'm not sure how these two components interact but thought perhaps django-storages isn't reporting upload progress in a way that django-progressbarupload expects.
