Pull Request Overview
This PR adds Kubernetes as a backend engine for Dubbo Admin, enabling pod-to-instance resource mapping through client-go's list-watch mechanism. The implementation transforms Kubernetes pods into RuntimeInstanceResources and maintains InstanceResource linkage via event-driven updates.
Key Changes
- Introduced Kubernetes engine with pod list-watcher that transforms pods to RuntimeInstanceResources
- Implemented event subscriber pattern to sync RuntimeInstance changes with Instance resources
- Refactored component ordering system and runtime startup to support concurrent component execution
