Specify and implement Docker-Upload-UUID
This changeset adds support for a header to identify docker upload uuids. This id can be used as a key to manage local state for resumable uploads. The goal is remove the necessity for a client to parse the url to get an upload uuid. The restrictions for clients to use the location header are still strongly in place.
