here, instead of implementing InterfaceProvider<>::BindToRequest explicitly this
class allocates a ContextInterfaceProvider which allocates + binds instances of
NetworkServiceImpls. i'm doing this as a member in order to allocate it when the
context becomes available

     return true;
   }
 
  private:
   scoped_ptr<mojo::NetworkContext> context_;
+  scoped_ptr<NetworkProvider> network_service_provider_;
