Remove NRF dependency from UPF

Lukas Rothenederrequested to merge
remove_nrf_dependency into develop

Change

  • clean-up code for reading old configuration type
  • UPF no longer resolves the NRF host at startup so as not to fail if the NRF is not started before the UPF.
  • UPF starts a timer to retry the NF registration if the registration fails.
