* Add watch-based feedback with dynamic informer lifecycle management
Implements dynamic informer registration and cleanup for resources
configured with watch-based status feedback (FeedbackScrapeType=Watch).
This enables real-time status updates for watched resources while
efficiently managing resource lifecycle.
Features:
- Automatically register informers for resources with FeedbackWatchType
- Skip informer registration for FeedbackPollType or when not configured
- Clean up informers when resources are removed from manifestwork
- Clean up informers during applied manifestwork finalization
- Clean up informers when feedback type changes from watch to poll
Implementation:
- Refactored ObjectReader to interface for better modularity
- Added UnRegisterInformerFromAppliedManifestWork helper for bulk cleanup
- Enhanced AvailableStatusController to conditionally register informers
- Updated finalization controllers to unregister informers on cleanup
- Added nil safety checks to prevent panics during cleanup
Testing:
- Unit tests for informer registration based on feedback type
- Unit tests for bulk unregistration and nil safety
- Integration test for end-to-end watch-based feedback workflow
- Integration test for informer cleanup on manifestwork deletion
- All existing tests updated and passing
This feature improves performance by using watch-based updates for
real-time status feedback while maintaining efficient resource cleanup.
