Add value "clusterRole.create" for skipping creation of cluster role & cluster role binding

@dherges Great idea. Thanks.

Your code is ok, but there isn't any CI process behind it for now, and you need to regenerate the helm package with the command:

helm package . -d ./docs

It isn't a significant change and you can do it without changing the version.

After it you need to change sha256 in the helm index file:

• calculate SHA256 for the new package:

  sha256sum k8spacket-0.1.2.tgz

• change it in the file: https://github.com/k8spacket/k8spacket-helm-chart/blob/master/docs/index.yaml#L8

@dherges In the meantime, I've added GitHub action for auto-release helm charts.

Your PR is merged and the possibility to omit the creation of clusterRole and clusterRoleBinding is available now.
