1. install kwok
2. install the KWOK stage CRs to reconcile nodes, jobs, pods
3. create fake DeviceClass and ResourceSlices
4. Once this is done, the test can start creating workloads to for the scale test.

Ran into a lot of issues in make this work:

1. the helm template create generates yaml files that have templates embedded for kwok. The cl2 template parser was thinking it is template for CL2, so had to escape all of those. Cursor with claude-4-sonnet helped a lot in removing these errors.
2. two templates, kwok.yaml and deployment.yaml were skipping namespaces when they were parsed by cl2 template parser, had to implement custom parser to workaround this error edit: debugged

TODO:

1. the test is leaving behind resources, need to clean it up edit: done

But apart from all of this, using README.md and trying examples directory works:

# ./run-e2e.sh cluster-loader2   --testconfig=pkg/dependency/kwok/examples/test-config.yaml   --provider=kind   --nodes=1   --report-dir=/tmp/kwok-test
