https-listener does not support proxy-address-forwarding

HttpsListenerService explicitly passes false to its superclass for proxyAddressForwarding and certificateForwarding, making it impossible to enable these features. For a security-sensitive application, we need a secure connection from our proxy to WildFly and we need WildFly to respect the headers sent by our proxy. It seems easy to support these options by reading them in HttpsListenerAdd and passing them to HttpsListenerService, which can simply pass them to the super constructor.
