Feature: Kerberos credential configuration in AMT

[matt-primrose]

Describe the bug 🪲
We want a way to configure Kerberos credentials into AMT so that we can manage AMT devices using Microsoft Active Directory accounts directly with the AMT device through our local network management console. Need to be able to configure groups and group access to AMT features based on AMT realms

Expected behavior
RPS is able to set specific Microsoft Active Directory group access to specific AMT permission realms during configuration.
