[BUG] Kubernetes beta feature not enabled

[grzesuav]

Describe the bug

kubectl get --raw /metrics | grep NodeLogQuery
kubernetes_feature_enabled{name="NodeLogQuery",stage="BETA"} 0

according to documentation

https://learn.microsoft.com/en-us/azure/aks/support-policies#unsupported-alpha-and-beta-kubernetes-features

AKS only supports stable and beta features within the upstream Kubernetes project. Unless otherwise documented, AKS doesn't support any alpha feature that is available in the upstream Kubernetes project.

I need this feature to make it easier the node debugging.

To Reproduce
Steps to reproduce the behavior:

1. Run command '...'
2. See error

Expected behavior
The feature is enabled

Screenshots
If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• Kubernetes version 1.30.5

Additional context

[grzesuav]

After some support conversations, I got the following clarification:

I wanted to provide some clarification regarding the support and enablement of features in Azure Kubernetes Service (AKS). Microsoft states that "AKS only supports stable and beta features within the upstream Kubernetes project. Unless otherwise documented, AKS doesn't support any alpha feature that is available in the upstream Kubernetes project."

However, it is important to note that this statement does not imply that these features are enabled by default.

Looking at this AKS release note, it mentions:
"Starting with Kubernetes version 1.30 and 1.27 LTS versions, beta APIs will be disabled by default when you upgrade to these versions. An option will be provided to explicitly enable beta APIs closer to the 1.30 release."

The response I received from support involved a series of manual steps (such as editing kubelet configurations, enabling feature gates by modifying kubelet flags in systemd unit files, etc.), which are far from an automated or user-friendly process. This approach raises concerns about the complexity and maintenance overhead for enabling such features manually.
