Andre Puschmann bed35c747c gnb,rrc: fix handling of DRB for reconfig/reestablishment 
the five_qi value received from the 5GC was not stored/passed when
the UE object was moved from one RNTI to another during e.g.
reestablishment. this makes sure the selected 5qi is passed over
during that process.

Andre Puschmann d854bbc22e enb,rrc: remove hard-coded SCG bearer config 
Use 5QI config when configuring secondary cell group bearer for NSA.
The 5QI used for this needs to match with the QCI used for the initial
LTE DRB.

This allows to use RLC AM over NSA.

Pedro Alvarez f9a2850d74 gnb,ngap: Added interface so the NGAP can pass a NAS message to the RRC

Also made sure that the RRC notifies the NGAP upon the end of the
reconfiguration procedure, to make sure that the NGAP sends the UE
context setup response.
