Kyma Telemetry auto-wiring

[vrdc-sap]

When Kyma Telemetry module is present on the cluster, automatically create a MetricPipeline CR that scrapes DCGM metrics from the gpu-operator namespace and forwards them to the user's existing metrics backend.

NVIDIA DCGM Exporter already ships GPU metrics (utilization, memory, temperature) inside the gpu-operator namespace. Today they go nowhere. With this feature, enabling the GPU module is enough - metrics appear in the user's dashboards automatically with zero additional configuration.

How

1. On every reconcile, check if MetricPipeline CRD exists on the cluster
2. If Telemetry is present, create a MetricPipeline pointing at gpu-operator namespace, forwarding to Kyma's internal OTel Collector
3. Delete the pipeline when GPU module is deleted

Open question

Confirm the internal Telemetry OTel Collector service endpoint - this is what we point the pipeline output at so metrics flow to whatever backend the user already configured in Telemetry.

Acceptance criteria

• Telemetry not installed -> no error, no pipeline, silent skip
• Telemetry installed -> MetricPipeline created automatically on GPU module install
• GPU module deleted -> MetricPipeline cleaned up
• Telemetry installed after GPU module -> next reconcile picks it up
• GPU metrics visible in user's backend with no manual steps
