[BACKLOG-400] only allow get and set of white listed session variables
[BACKLOG-194]
 - Reverted RepositoryFieAdapter due to static methods and its usages. Updated unit tests.
 - Fixed project compile due to removed jmeter dependency from ivy. RepositoryResource, UserRoleListResource and UserSettingsResource still had it.
 - Fixed tests due to removed java 7 exception on FileService. Test wasn't updated
