feat: cilium network load test pipeline

[huntergregory]

Goal

Validate scenario with induce heavy pod traffic on many nodes.

Validations

TODO: implement

1. cilium pod is ok.
2. Datapath is ok (e.g. conntrack).
3. Network observability (Hubble) metrics are ok.

Validations

TODO: implement

Topology

Topology when nodes=2, serversPerNode=2, clientsPerNode=2, namespaces=4, deployments=2.

You can specify queries per second coming from each client as well.

Topology Parameters

• nodes
• servers per node
• clients per node
• queries per second (per client)
• namespaces. There is 1 service per namespace, and all server deployments in the namespace are its backend pods.
• deployments. A value of N means N client deployments in the cluster, each talking to a corresponding server deployment. Controls the number of cilium identities.

Dependencies

Requires pending CL2 support for scraping hubble metrics.

Implementation Notes

Other Parameters

• whether to apply a CNP that generates DNS metrics (requires ACNS security agent)
