[BUG] Not able to delete Hybrid AKS clusters. Only node pools gets deleted after that the resource bridge is broken.

[The-TeQnician]

Describe the bug I am not able to delete Hybrid AKS clusters from Azure Stack HCI. If i want to delete a successfully deployed cluster via the portal it only deletes the nodepool workers and then stops. Load balancer and control plane stay behind and after 15 to 30 minutes the delete job fails with an undefined error. After that the resource bridge stops working and new deployments also fail.

To Reproduce Steps to reproduce the behavior:

1. From the portal go to the Hybrid AKS cluster
2. Click on delete
3. Delete jobs runs and nodepools get deleted.
4. Then the delete jobs keeps on running and fails

Expected behavior When i delete an hybrid AKS cluster from the portal i expect it to work. Node pools, Load Balancer and Management pane deleted from HCI cluster and objects removed from the portal.

@The-TeQnician we rolled out a fix for the delete issue. One of the resourceTypes: provisionedClusters/upgradeProfiles was under a feature flag and since your subscription was not registered for that feature flag, azure was not able to delete it, and in turn it was blocking the delete of the parent resource (provisionedClusters) as well. We have removed that feature flag and rolled out the change and you should be able to see it as a part of Microsoft.HybridContainerService RP in your subscription now (You can check az provider show -n "Microsoft.HybridContainerService" to see if it has "resourceType": "provisionedClusters/upgradeProfiles") Can you please retry the delete and let us know how it goes?

Hi @HariPrasadV, i have been testing this and it seems to fixed the issue when the resource type is registered! Great thanks!!
