If http_proactive_auth flag is set and there is a username but no password in the proxy url, then interactively ask for the password.
This makes possible to not have the password written down in http_proxy env var or in http.proxy config option.
Also take care that CURLOPT_PROXY don't include username or password, as we now set them in the new set_proxy_auth() function where we use their specific cURL options.
