invoking the AKS cluster query; when the resource group is missing, set
AZURE_CLI_DESIRED_STATE=true and return the absent-cluster result instead of
propagating an az aks list failure. Preserve the existing run_az_with_retry

Why did you write this? I appreciate the tests but let's not invent a new testing framework for this change

You’re right — this was overbuilt for a shell-only change. I removed hack/test-azure-cli-retry.sh and its validator hooks in commit 06a7a66, leaving the production step changes intact and relying on the repository’s native ShellCheck, registry metadata, config validation, and rehearsal/CI checks. The later AKS missing-resource-group review finding was also addressed in 8e6055b.

This pull request was generated by the Product Reliability Agent. To help us improve product stability and CI, please focus review on functional correctness and material concerns. The agent will automatically address feedback, but we’d appreciate keeping non-blocking nits from delaying an otherwise correct PR. Within two business days, please merge, provide blocking feedback, or close the PR with a reason.
Summary
The Azure CLI calls used by the HyperShift/AKS CI steps can fail on transient DNS or lower-level transport errors. This change adds bounded retries to the affected step-registry scripts and keeps resource mutations safe by reconciling desired state before retrying ambiguous responses.
Scope
The change is limited to four Azure/AKS step-registry scripts that execute the affected CLI operations. No bespoke test framework is included.
