Enhance RADIUS v2 Sensor to comply with RFC 3579 Message-Authenticator

As a Network Engineer, I want the RADIUS v2 sensor to support RFC 3579 Message-Authenticator validation so that I can monitor RADIUS servers with enhanced security and ensure authentication packet integrity in my network infrastructure. The client (PRTG Sensor) computes the hash (HMAC-MD5) from its own packet and then adds the attribute as a signature to the request. This is required for secure implementations of RADIUS.

    We recently had to enable the Message-Authenticator during the hardening our RADIUS configuration. In the past we monitored the the Status of our RADIUS Server with this sensor. Now this is no longer possible.
