The OCM-io/ACM argocd-agent addon is currently configured to use separate images for the principal (hub cluster) and the agent (spoke cluster components), but argocd-agent upstream project has since merged those into a single binary.

We need to update our addon manifest to reference the new unified image and separately  to synchronize our RBACs with the various argocd-agent upstream PRs that introduced changes to permissions.

The goal of this task is to ensure our OCM-io/ACM argocd-agent addon installs successfully against the latest upstream release, incorporating both the unified binary, the individual RBAC updates and other misc changes that prevents the addon from being successfully deployed (with the latest upstream changes).
