I'm not sure I understand this comment.  URLRequestInterceptors added through
URLRequestFilter are not avoided, also g_interceptor_for_testing is not avoided.

Comment updated.  Wrote the comment before the CL to make the filter use
interceptors.  It avoids the interceptors attached to
URLRequestInterceptingJobFactories.

+    storage_.set_job_factory(new net::URLRequestJobFactoryImpl());
 
     return net::OK;
