for proper CNF DAY0 and Day1 configurations the interface N1, N2, N3 should be added to the generation process. 

Such interface are needed to configure the endpoints between UU, O-CU-UP, O-CU-CP and the corresponding 5G-Core functions: AMF (Access and Mobility Management Function) and UPF (User Plane Function)

For test purposes, can be assumed that there is one 5G-Core for each Near-RT-RIC.
