When using a centralized ArgoCD instance in the control plane, it may sometimes be necessary to configure an ArgoCD Application as a hook, e.g. running an application as a post-sync hook, and specifying a destination cluster to execute jobs in a data plane cluster.
But right now the health check for this CRD is not supported in ArgoCD (or Helm either).. which makes it hard for the controller to determine whether to clean up the hook or not when using the delete policy HookSucceeded.
