Add Kueue and Cluster Autoscaler on AKS example

[AaronLiChen]

Summary

• Add an end-to-end example for running batch jobs on AKS with Kueue admission control and the cluster autoscaler
• Kueue gates jobs and, via a ProvisioningRequest AdmissionCheck, asks the cluster autoscaler to atomically provision capacity before the job is admitted (provision-first, avoids half-scheduled gangs)
• Three modules walk through infrastructure, queue + provisioning-gate configuration, and workload submission

What's included

Module	Content
1 — Infrastructure	AKS cluster with an autoscaling node pool + Kueue install (Helm)
2 — Kueue Queues	ResourceFlavor, ProvisioningRequestConfig, AdmissionCheck, ClusterQueue, LocalQueue
3 — Workload	Suspended Job that triggers an atomic scale-up via ProvisioningRequest

Follows the structure of the kueue-and-ray-on-aks example. A companion how-to in the AKS docs references this directory.

Test plan

• Manifests apply cleanly on a fresh cluster
• Kueue creates a Workload + ProvisioningRequest for the suspended Job
• Job admitted and runs once nodes are provisioned

• The Job uses the pause image, which never exits, so the Job will not reach Complete/COMPLETIONS 3/3 as described in the READMEs. Use an image/command that terminates successfully so the example can complete end-to-end.
