TE-14.6: gRIBI Scaling - all scenarios but with minimal scaling parameters

Summary

Validate gRIBI scaling requirements using a minimized scale setup (Target Down/Minimized).

This test shares its topology, baseline configuration, procedures, test cases, and OpenConfig specifications with the other gRIBI full-scale targets. See the Generic gRIBI Scaling README for full details.
