Update Issue 265 introduced a number of new methods so that the application can instruct the container to avoid managing and locking the newly created session. Also added new asynchronous methods taking a session idin parameter instead of the full session to avoid locking the session when getting it through SipSessionsUtil.getApplicationSessionById
