This PR addresses the querystring mutilation part of #3:
The default get_upstream_http_options() implementation no longer sets params.
Instead, it calls the new get_upstream_url_with_query function whose default implementation appends the verbatim client querystring to whatever the user-defined get_upstream_url() function returns.
cc @jokull – would you like to take a look at the implementation? I think this shouldn't break your current code either.
