Description

Something to consider if we want: should the etag and version from the initial getObjectMetadata call be propagated to the actual CopyRequest if they are not already known

That way, if we rename() a file and its etag/version is not known, we can fix them for the next stage of the operation. Relevant given we are copying metadata over, and for resilience to changes while the copy is taking place
