Kubernetes v1.36: Advancing Workload-Aware Scheduling

Kubernetes v1.36 introduces workload-aware scheduling improvements, including a new PodGroup API that separates runtime state from the Workload API. This allows for atomic workload processing and paves the way for future enhancements. The update also includes topology-aware scheduling, workload-aware preemption, and Dynamic Resource Allocation (DRA) for PodGroups. The Workload API now serves as a static template, while the PodGroup API manages runtime state. This change improves performance and scalability.
