MT#65662 Support domain/profile/subscriber level inheritance (group load)

For grouped loading of preferences, add support of the levels:
- domain
- profile
- subscriber

This allows to be consistent with the existing caller/callee preferences
loading (of the subscriber level) which takes other levels of inheritance
into account.
