Allow custom rules for (Cluster)Role to be provided/exposed in values.yaml helm chart

**Description**

I may be the only one with this use-case but I would love it if I could specify the rules for pod-launcher (give it extra permissions on kube)

**Use case / motivation**

I'd like to give pod-launcher permission to create and monitor Job type as well as regular pod type.
Currently in my deployment I just apply a post-deploy patch to the ClusterRole with the added perms I want but this feels hacky to me. If there's a way to do this better please let me know!

**Are you willing to submit a PR?**

**Related Issues**

Start by reading the Helm chart's values.yaml and the ClusterRole/Role definitions that configure pod-launcher permissions. Add a values.yaml option for custom rules and verify that the configured rules are exposed in the rendered ClusterRole or Role, including permissions for Jobs.
