IP Traffic not working, tun if established by NRUE 

Updated the configuration files. Added a sleep to
ensure that the LTE UE gets attached to the EPC
before the bearer is modified to be gNB. Updated
the ifconfig tunnel up command to be brought up
by the NR UE socket when in NSA mode. Lastly,
started the gNB PDCP layer in S1 mode.
