Melissa Elkadi 7f2e622b0e Sending tunnel interface 'up' command to NR UE 
Once the LTE UE's tunnel interface with the EPC
is ready to be established, if we are in NSA mode,
we do not want to launch the tunnel interface
from the LTE UE side, but in the NR UE. Via itti_msgs
we send the string containing the tunnel interface
'up' command to the NR UE and bring it up from the NR UE.
