Public bug reported:

During an image upload, if an exception occurs while uploading a chunk
to swift, the glance swift store aborts the upload and deletes all the
chunks that were uploaded thus far. Though this is the desired behavior,
it maybe worthwhile to retry the failed chunk before deleting other
chunks to account for intermittent connection errors. This will save a
lot of time and bandwidth especially in the case of large images.
