The Amarisoft root prompt contained '#' (as usual for root). However, to
integrate this into the UE management logic (cls_module_ue.py), we are
forced to use '$'. We changed the root command prompt to use '$', and
therefore change it here as well.

- there are extra variables in gnb_entrypoint.sh to resolve FQDN which
  are superfluous
- allowing nrue config to use gnb fqdn and ip-address
- rfsimulator parameter is not used in all docker-compose so it should be optional
- make amf ip-address optional
