Technical summary

The Kubernetes Python client attempts to JSON serialize a ConfigNode in exec_provider configuration.

Convert ConfigNode values to plain dict/list/scalar data before passing exec_provider data to JSON serialization.

The failing object is ConfigNode, so the patch should normalize that wrapper at the kubeconfig boundary.

The patch passes kubeconfig wrapper values through unwrap_config_node before JSON serialization and key lookup. The helper returns the plain dict, list, or scalar value so exec_provider data is serializable.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import kubernetes; print('smoke test OK')"
