Is your feature request related to a problem? Please describe

ArgoCD + deploy clusters with Crossplane is a popular choice of deployment model. We should make an example of it with EKS addons and other needed things.

Describe the solution you'd like

1. Use ArgoCD annotation based tracking to avoid unwanted pruning.
2. Use Crossplane + packages (possibly custom) to provision EKS with popular addons installed.

Use ArgoCD annotation based tracking to avoid unwanted pruning

Can you expand with an example on what "unwanted pruning" your referring?

See: crossplane/crossplane#2121
Pretty much comes down to the relationship between ArgoCD's pruning mechanism and XR claims where Argo was not aware of claims "owning" XRs. The end result is that claim is created but XRs is deleted when pruning is enabled.
