LDEV-3335, LDEV-3334: Use SSO mechanism introduced in WildFly 9. Do not create web.xml files with XDoclet as it can not produce them based on 3.1 schema. Use static ones instead. Make SessionManager just a proxy to webserver's HTTP session. Remov custom shared sessions and JSESSIONIDSSO cookie as they are obsolete. Remove own session monitoring as the container should take care of invalidation. Move injecting UserDTO into session to SsoHandler intead of UniversalLoginModule as an authentication request may not reach the latter due to WildFly credentials caching.
LDEV-3275: Add SsoConsumer in LAMS Central as requests (index.jsp, index.do) immediate after j_security_check are also being authenticated. They also are considered an authentication attempt, but they bypass shared session creation in SsoProducer and it causes errors. This was addressed by a simple check - no shared session in UniversalLoginModule, no authentication attempt.
