[BUG] Unable to disable prometheus stack on cluster after adding azure container storage extension.

[muadnan]

Describe the bug
Unable to disable prometheus stack on cluster on which prometheus is already deployed after adding azure container storage extension.

To Reproduce
Steps to reproduce the behavior:

1. Enable azureContainerStorage extension.
2. Disable prometheus stack using:
   az k8s-extension update --cluster-type managedClusters --cluster-name <cluster_name> --resource-group <resource_group_name> --name azurecontainerstorage --config base.metrics.enablePrometheusStack=false

Expected behavior
Prometheus stack should be removed and all resources should be deleted including CRD's.

Environment (please complete the following information):

• CLI Version 2.67.0
• Kubernetes version 1.31.2

Additional context
There should be an option to disable prometheus stack while enabling azure container storage.

@muadnan , clarifying question - if the above command is being used to disable customer's own Prometheus instance or Azure Container Storage's Prometheus stack? The command is purposed to do the later.

@saurabh0501 The above command is used to disable the kubePrometheusStack deployed by azureContainerStorage as mentioned in the documentation: https://github.com/MicrosoftDocs/azure-docs/blob/main/articles/storage/container-storage/enable-monitoring.md

@saurabh0501 when I changed the config parameter base.metrics.enablePrometheusStack=false it is not actually reflected on the deployed helm release on the AKS. I tried changing other parameter:
base.metrics.metricsExporter.enabled=false
it is working fine. So, there is a bug due to which base.metrics.enablePrometheusStack=false not reflecting on deployed release of azureContainerStorage.

@olsenme @muadnan, we are currently working on a fix for this issue. We have root-caused the issue, and the fix will be available as part of the Azure Container Storage's next release. I will share more details once I have the plan available for our next release.
