Delete Terminating hanging namespace

clean up content in finalizer section via json/yaml file or directly edit namespace via kubectl

Methold below always works
Assuming local is terminating...
kubectl get namespace local -o json > local.json         
kubectl get namespace local -o json \
            | tr -d "\n" | sed "s/\"finalizers\": \[[^]]\+\]/\"finalizers\": []/" \
            | kubectl replace --raw /api/v1/namespaces/local/finalize -f -
