CI: adding RF simulator skeleton on 5G NR gNB and UE
RF simulator testing is now enabled in the pipeline
- gNB is started in noS1 in one VM (after the build stage)
- nr-ue is started in noS1 in another VM
- Detection of tunnel interfaces is done
- Simple DL iperf test : 30Kbits/s requested throughput --> the target can be updated later on when performance is better
No ping operations, no UL iperf yet
