Allow a non-200 (or non-407) response for a CONNECT request from an HTTPS proxy

to be consumed by chrome.  Among other things, this will allow the proxy to
inform the user that the hostname could not be resolved or similar conditions.

This adds a new OnHttpsProxyTunnelConnectionResponse method to
StreamRequest::Delegate which is invoked when an HTTPS proxy returns a non-200,
non-407 response.  The method is called with an HttpResponseInfor argument to
access the request headers, and an HttpStream argument to access the response body.
