RADIUS server using APM to authenticate users

Thanks for keeping all the APM logic in one place, it was easy to replace with my 2FA iRule logic and update it to v1.4. One thing I amended was the duplicate package logic, since we are sometimes authenticating "Time-based One Time Passwords". I only store a response at the end if it wasn't an "Access-Accept", and only for 1 second maximum life time. Thanks for the heroic effort!
