Optimize checksumming of Object Stored Packages
https://gitlab.com/gitlab-org/gitlab-ee/issues/10586#note_179615627
never assume the ETag is always the MD5 hash
consider the MD5 while streaming file
Question: What about reverification? I.e. for local files, we regularly re-checksum primary data and then re-verify secondary data against it. Can this be done efficiently with Object Storage?
