WVI-25: Remove servlet configuration from Central, make lams_saml be almost completely standalone. Add DB tables and access layer for storing user "office" parameter. Make lams_saml a WAR instead of JAR as it needs access to Central context beans and introduces own services. Make configuration be stored in WAR and accessed internally by Java code instead of deploying it in web content and access by HTTP. Put "group" parameter in sesssion when user accesses SamlServlet for the first time, before redirecting to IdP log in page. This parameter is later used for registering user. Add wrapper method in Integration service allowing creation of group withou external server prefix.
