CR-3912 OPENIG-95 && OPENIG-94
Remove or hide Servlet/Filter integration since it complicates the configuration model
Consider merging SAML federation support into single OpenIG application

- openig-core pom file : removed <packaging>jar</packaging> as jar is default packaging.
- HandlerServlet.java : modified as the wrapped servlet may have already committed its response w/o creating the OpenIG response. 
(see comment for support 94-95)
- openig-federation-war renamed to openig-saml.
  -> FederationServlet and FederationServletAdapter added in new package org.forgerock.openig.handler.saml
- openig-saml pom file : removed <packaging>jar</packaging> as jar is default packaging. (was a war before)
- openig-war pom file : removed dependencies on assertj, testng, javax.servlet. Added new dependency on the openig-saml's jar.
