Permanently remove a JBoss node from configured http proxies

When a JBoss node is restarted it advertises the web apps deployed to it as being available for the http proxy to route traffic to them. This is undesirable when a JBoss administrator needs to keep a JBoss node out of service for validation and/or troubleshooting steps. Mod_cluster needs to offer some mechanism to permanently remove a JBoss node from any configured http proxy until a JBoss administrator manually adds it back.
