Use user supplied options when resending authenticated requests

Hooks sometimes have to send requests (e.g. when responding to a 401 during
authentication).

All keyword arguments should be passed along when hooks are dispatched so that
if a user wanted to use a timeout, stream, specify a cert location with the
verify flag, etc, their specification can be followed.
