Rel_19 TS28.623 CR 0377 Rename attributes for 5GC UE level measurement
requested to merge Rel19_TS28.623_Rename_attributes_for_5GC_UE_level_measurement into Integration_Rel19_SA5_156_YANG
Add all Rel-18 updates for TS 28.111, 28.623, 28.541 to the REL-19 branch. As the TS documents do not yet have an Rel-19 version (but the Rel-19 Forge branch is already separated) all Rel-18 corrections should be automatically copied to the Rel-19 branch too.
