This commit adds the `skipHooks` option to the helm chart support in order
to expose the --no-hooks flag introduced to Helm in [1].
Using Kustomize to inflate a Helm chart would in some situations result in
different results than using `helm install`. This is because `helm
template`, by default, will render chart tests in the `templates/test`
directory, which can lead to undesired resources in the output.
See [2] for additional discussion.
