What are you trying to achieve or the steps to reproduce?

Configuring a route with route.options.timeout.socket smaller than route.options.payload.timeout

 server.route({
        method: 'POST',
        path: '/',
        options: {
            payload: {
                timeout: 1000
            },
            timeout: {
                socket: 200
            }
        },
        handler: (request, h) => {
            return 'Hello World!';
        }
    });

What was the result you got?

Causes the following error to be throw:

AssertionError [ERR_ASSERTION]: Payload timeout must be shorter than socket timeout

What result did you expect?

I expected to be able to configure the route.options.timeout.socket to be smaller than route.options.payload.timeout. The payload timeout controls the total payload reception time; where-as route.options.timeout.socket is actually the "idle socket timeout", not the "total time socket is open timeout". For example, we should be able to configure the payload to be sent within 1 second, while ensuring that the socket isn't idle for 500ms during the entire duration of the request and response.
