Carlo Galiotto aa979708a0 rrc-nr,test: add fnc to trigger send_security_cmd 
The SecurityModeCommand procedure was previously initiated by the
RRCSetupComplete msg. However, it should be trigger by the NGAP
through the InitialContextSetupRequest msg.
This commit implements this change and fills in the function of
the NGAP interface that starts the SecurityModeCommand procedure
