invoke_nativehandle_options called with invalid socket handle

[ce-bu]

Hello, I need to set a socket option before the connection is established. I tried the invoke_nativehandle_options callback but the socket handle is invalid at that time.Is there a way to achieve this currently? Currently my workaround is to change async_connect in http_client_asio and invoke a callback on http_config (a new one) where I can call socket_set_option() but that would require changing the library. If you think this is useful I can submit a PR Thanks
