[swift][s3][multipart] S3 multipart re-upload leaves orphan segments

Hello,

I understand that this is a known issue for some time, but I dont know if it has been resolved. As far as I know stable/2023.2 still has this problem, is there any related work?

We think there are two fronts: - Segments of incomplete multipart, forgotten by the user - Completed re-uploads

We plan to fix those: - Using the object-expirer in a new middleware - Deploying workers to review all files, checking if they are still in use

What are your thoughts?
