Make UPF configuration more dynamic and more user-friendly
- Replace static config files init.conf and upf_profile.json with dynamically created configuration files
- Add create_configuration.py to dynamically create the configuration based on environment variables
- Support several different UPF configurations (A-UPF, I-UPF, UL CL, standard UPF)
- Do not require correct order of docker interfaces anymore (IP address is assigned based on subnet)
- Simplify entrypoint.sh
