[1] Web whois should redirect to www.registry.google. whois.registry.google also points to the proxy IP, so redirecting to whois.registry.google just makes it loop. Also allow HEAD in web whois request in case that is used in monitoring.
[2] Separately, there's a bug introduced in [] where exception handling of inbound messages is moved to HttpsRelayServiceHandler. However the quota handlers are installed behind the HttpServiceServiceHandler in the channel pipeline, therefore the exception thrown in quota handlers never got processed. This results in hung connection when quota exceeded.

When EPP SSL handshake is unsuccessful, #channelInactive is called but there are no quotas to return, because quotas are only leased upon the first #channelRead. There is no need to log a warning and throw an exception in this case because the handshake exception would have been thrown already. Throwing a second exception just crowds the log.

When a quota request is rejected, increment the metric counter by one.
Also makes both frontend and backend metrics singleton because all the fields they have a static.

The quota handler terminates connections when quota is exceeded.
The next CL will add instrumentation for quota related metrics.
