Introduce new UE context status state at the eNB for the NSA procedure 

- UE context status enters RRC_NR_NSA_RECONFIGURED state, after the eNB receives an RRCConnectionReconfigurationComplete message including the
scg_ConfigResponseNR_r15 container.
- Use this state to avoid triggering sGNB Addition Request multiple times
