Add prometheus node to the Containerlab topology, scraping the gnmic exporter (172.16.0.70:9273) at 5s interval with relabeling to clean device/interface/neighbor_address/vlan/mac_address/afi_safi labels. Validated against BGP and system metrics confirmed in #44. Existing external Prometheus instance stays untouched in parallel. Refs #45
