Title: Azure 12 9 invalidate loopback

Please merge this changes into master
I have added new callback to GlobalSession::Directory.session_invalidated(invalidate_uuid, new_uuid)
In GlobalSession::Rack::Middleware.update_cookie, I have generate new global_session object if it is not valid, then execute GlobalSession::Directory.session_invalidated with invalidated_uuid and newly created global_session.id. And save into cookie newly created global_session object.
