Thanks for this PR, @jspdown !
This chart allows to choose between namespace rbac or cluster-wide rbac. It seems this PR covers only cluster role.
Would you please update role.yaml accordingly ?

@mloiseleur Thanks for your review. I've updated the PR accordingly.

Please note that I made some cleanup as well:

• Removing duplicated resource rights (services and endpoints)
• Removed resources that are no longer supported (edgeingresses, deployment, statefulsets, and daemonsets)
• Removed write access on ingresses
