Description

sonic_yang_mgmt follows these guidelines in order to convert from config_db to config_yang and vice versa.
in GCU we rely on the same guidelines to convert from config_db path to config_yang xpath and vice versa.

There were modifications to how sonic_yang_mgmt converts data recently, and these changes are not supported by gcu, the changes are the following:

• Supporting Type_1_list_maps_model SONiC CBF MAPs Yang sonic-buildimage#9116

Please make sure to add tests for CABLE_LENGTH and other tables that are affected by this change.
