    Handle PDU Session Resource to Setup Failure in (PDU Session Resource/Initial Context) Setup Response
    
    * add function to check whether cu-up is connected
    * add functions to send the relevant response messages with the failed list
      e.g. to fill PDU Session Resource Failed to Setup items
    * set return value of trigger_bearer_setup to bool and handle the
      failure by sending setup response messages with list of PDU sessions failed to setup
      i.e. send failed list of items when no CU-UP is associated to the CU-CP
      note: it considers all PDU Sessions as failed to setup in the considered failure scenarios
    * e.g. send a list of failed PDU session resources in the response message to reject
      PDU Session Resource Setup in rrc_gNB_process_NGAP_PDUSESSION_SETUP_REQ
    * the Initial Context Setup has a Failure message, but for the considered failure scenario
      when no CU-UP is available the current design is just sending a list of failed to setup
      items in the Response message
    * transfer PDU Session Resource/Initial Context Setup Request NAS PDU to UE
