This builds on the previous work that sets up the body streaming for the put object and put part requests. This adds the auth and checksum readers to postpone the v4auth checks and the content checksum until the end of the body stream. This means that the backend with start reading the data from the body stream before the request is fully validated and signatures checked. So the backend must check the error returned from the body reader for the final auth and content checks. The backend is expected to discard the data upon error. This should increase performance and reduce memory utilization to no longer require caching the entire request body in memory for put object and put part.
