Kubernetes v1.37: Scale Workloads to Zero with HorizontalPodAutoscaler

Kubernetes v1.37 includes API support for horizontal autoscaling of workloads down to zero replicas. This feature is now Beta and enabled by default.

An extended resource name can be set directly on a DeviceClass, and Pods requesting it get matched to a device through DRA with no ResourceClaim needed on the workload's part.
