🐛 [BUG] - Organization is not cleaned up properly

[IvoGoman]

Priority

(Medium) I'm annoyed but I'll live

Description

As a admin I can delete an Organization so that the namespace and all resources are cleaned up accordingly.

The Organization is left hanging when it has been deleted. The EnsureDeleted requires that the Delete condition is set. Currently this is not the case.

Also the provisioned admin team cannot be deleted, as the propagation reconciler is left:

 finalizers:
  - greenhouse.sap/propagatedResource

The PropagationReconciler should not add the finalizer, if there are not clusters to propagate to. Also it should cleanup & remove the finalizer, once the propagated resource is being deleted.

Reproduction steps

1. Create an Organization
2. Wait until resources are created
3. Delete the Organization
4. Organization & all created resources including the namespace should be deleted

Manifests

apiVersion: greenhouse.sap/v1alpha1
  kind: ...
