k8s: Kubernetes 1.35: In-Place Pod Resize Graduates to Stable

Kubernetes 1.35 graduates In-Place Pod Resize (In-Place Pod Vertical Scaling) to stable (GA). The feature makes CPU and memory requests and limits mutable on a running Pod (via a resize subresource), often without restarting containers. This enables non-disruptive resource adjustments, more powerful autoscaling (e.g., VPA InPlaceOrRecreate), transient boosts like CPU startup boost, and better resource efficiency. The release also adds prioritized retries, allows memory limit decreases (best-effort OOM protection), alpha support for Pod Level Resources, and new kubelet metrics/events. Work remains on runtime support, scheduler/kubelet races, expanded feature support, and integrations with autoscalers and other projects.
