[JBoss JIRA] (MODCLUSTER-531) Eliminate automagic

Unfortunately, this IMHO often backfires quite significantly resulting in configurations that are: > # insecure (listening on all interfaces, allow from all, default security key "changeme!") > # difficult to debug (not clear what is the actual configuration) > # unstable installations (seemingly unrelated aspects like adding an interface or connector break the previously working configuration) > h1.

Advertised address of the proxy > There were multiple bugs in the past, where 0.0.0.0 would be sent in the advertise mesages, now if its not explcit in the VirtualHost or passed in to ServerAdvertise, it automagically picks a non-local interface. Such configurations should be disallowed. > h5. Advertise interfaces > The interfaces are not explicit and advertise messages could be sent/received on more interfaces (related MODCLUSTER-487). This is also problematic when trying to move to DatagramChannel interface, which requires interfaces to be defined explicitly (MODCLUSTER-502). We can require this explicitly. > h5. Connector address > If bound to any-address, the address is inferred from the proxy connection as the local address. This is solved in the default WildFly configuration as its explicitly bound to a interface. > h5. Connector selection > -This is solved in WildFly where selection is explicit. In tomcat this causes problems like MODCLUSTER-457 when WS requires http yet ajp is automatically selected by default. We can make this explicit.- DONE MODCLUSTER-457 > h5.
