Opened two ports (30010 and 30011 by default) that handles HTTP(S) GET requests. the HTTP request is redirected to the corresponding HTTPS site, whereas the HTTPS request is redirected to a site that supports web WHOIS.
The GCLB currently exposes port 80, but not port 443 on its TCP proxy load balancer (see https://cloud.google.com/load-balancing/docs/choosing-load-balancer). As a result, the HTTP traffic has to be routed by the HTTP load balancer, which requires a separate HTTP health check (as opposed to the TCP health check that the TCP proxy LB uses). This CL also added support for HTTP health check.
There is not a strong case for adding an end-to-end test for WebWhoisProtocolsModule (like those for EppProtocolModule, etc) as it just assembles standard HTTP codecs used for an HTTP server, plus the WebWhoisRedirectHandler, which is tested. The end-to-end test would just be testing if the Netty provided HTTP handlers correctly parse raw HTTP messages.
Sever other small improvement is also included:
[1] Use setInt other than set when setting content length in HTTP headers. I don't think it is necessary, but it is nevertheless a better practice to use a more specialized setter.
[2] Do not write metrics when running locally.
[3] Rename the qualifier @EppCertificates to @ServerSertificate as it now provides the certificate used in HTTPS traffic as well.
