Skip putting non-primitive values from CBS config into PRH app environment

Non-primitive properties are currently not used by app and cause serialization failure on 'actuator/env' endpoint.
The serialization issue is caused by fact, that swagger enforces switch to jackson and there are no proper gson's JsonObject serializers registered.
