IMO, etag is designed for client side cache. A typical usage: if the file
on the server has no actual change, the client will use the cache and the
server does not need to send the file content again. While for a storage
service, we also need some some similar mechanism at server side. In this
way, the client do not need to upload unchanged content to the server.
