This is available only on MinIO as an extension to the Expiration feature. The following rule makes it possible to remove all versions of an object under 
the prefix `user-uploads/` as soon as the latest object satisfies the expiration criteria. 

> NOTE: If the latest object is a delete marker then filtering based on `Filter.Tags` is ignored and 
> if the DELETE marker modTime satisfies the `Expiration.Days` then all versions of the object are
