feat(ci): adding automation for 5G NR SA L2 simulator with Proxy

- Adding new templates for nFAPI in gNB and NR-UE images
  - Better entrypoint for NR-UE (alignment on others)
  - New Test method: StatsFromGenObject
  - At deployment, image name, size and date are printed
  - Initial scenario with 1 NR-UE and just ping operations
  - Trigger new child sub-pipeline for L2-sim-5G tests
