/**
* Module brief:
* This module is used to add RRCRelease commands to the telnet server in the
* absence of full support for E2SM RAN Control (RC) function in the RIC.
* This provides similar functionality to the ORAN.WG3.E2SM-RC-R003-v05.00
* 8.4.5.4 RRC Connection Release Control which is initiated by the RIC.
*
* Implementation notes:
* We refer to the method call rrc_gNB_generate_RRCRelease at rrc_gNB_NGAP.c
* during rrc_gNB_process_NGAP_UE_CONTEXT_RELEASE_COMMAND message generation.
