add a script to test policy-generator local

[ch-stark]

e.g like below it helps to use PolicyGenerator more easily:

mkdir -p ${HOME}/.config/kustomize/plugin/policy.open-cluster-management.io/v1/policygenerator

curl -L \
  -o ${HOME}/.config/kustomize/plugin/policy.open-cluster-management.io/v1/policygenerator/PolicyGenerator \
  https://github.com/stolostron/policy-generator-plugin/releases/download/v1.8.0/linux-amd64-PolicyGenerator
chmod +x ${HOME}/.config/kustomize/plugin/policy.open-cluster-management.io/v1/policygenerator/PolicyGenerator

curl -s "https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.sh"  | bash


sudo chmod a+x kustomize /usr/local/sbin
sudo cp kustomize /usr/local/sbin

Once the files are created in the same directory, run the following command to generate the policy:

kustomize build --enable-alpha-plugins
