The OpenShift installer includes a autoscaling:DescribeAutoScalingGroups IAM permission which I believe its not used and carried over from something that may have existed in Hive a long time ago or maybe not at all.

Reference installer commit

I don't see references for API calls for it Hive in the code and I chatting with the Hive team in slack they too don't see it.

Done criteria:

• Test creating a cluster with ROSA (Hive)
• Create enabling auto scaling
• Destroy cluster and ensure everything was cleaned up
• Validate with CloudTrail that the IAM call was not used
