LDEV-3275: Deploy Jdom as a WildFly module. If the 1.1.2 version delivered with WildFly is used, code changes are required as API is not the same. So current version 0.7 is left. Same situation is with Quartz. Upgrading 1.5.3 -> 2.2.1 requires code changes.
LDEV-3275: Deploy JBoss Web Server as a WildFly module. This is a fragile part as JBoss Web Server was a base for previous JBoss Application Server versions. Not it is Undertow so the Web Server is used here as a plain library for SSO valve and JSON code.
