auth-token: expose fetched token in unified way into request attribute.
- This will allow re-using exposed access token for HTTP views in single place
- We will support also exposing tokens from url if special _auth_token will be used as url param
- We'll no longer require double logic for extraction of URL/HEADER auth-tokens and have a single place to extract it.
