informer not shutting down properly when RG is deleted

[a-hilaly]

Description

When a ResourceGroup is deleted, the dynamiccontroller's informer for that RG's corresponding GVR isn't properly shutting down. After calling UnregisterGVK, the informer appears to still be running despite cleanup attempts. This could be an upstream Kubernetes client-go bug or an implementation issue in our shutdown logic.

Current behavior in dynamiccontroller.UnregisterGVK:

• Calls wrapper.shutdown() to cancel context
• Calls wrapper.informer.Shutdown()
• Removes informer from maps/caches
• Informer still appears active

Investigation steps needed:

• Check if client-go's DynamicSharedInformerFactory Shutdown is working correctly
• Verify our context cancellation propagation
