We need to better integrate ClusterPermission resource into ACM

https://github.com/open-cluster-management-io/cluster-permission

After some initial investigation the following topics need to be resolved:

• Bundle it into the MCE instead of ACM.
• Update the API to fit more use cases
• Rewrite from hub controller into an addon agent similar to managedserviceaccount (MSA)
• Dedicated doc section (right now its hiding under GitOps section)
• Remove tech preview tag.
• Maybe UI (it should integrate with MSA)
