Add a 200 OK response at /healthcheck #145

Closed bkoski closed 7 years ago

Google Cloud Platform recently added support for WebSockets behind their L7 HTTPS load balancers, but a em-websocket server cannot be deployed unless it has an endpoint that responds with 200 OK.

This PR adds a /healtcheck response in a similar pattern to the Flash crossdomain response. This endpoint is useful for various systems that prefer HTTP rather than TCP healthcheck probes.
