      * Previously, the Cloud Credential Operator (CCO) checked for a nonexistent `s3:HeadBucket` permission during installation on {aws-first}.
      When the CCO failed to find this permission, it considered the provided credentials insufficient for mint mode.
      With this release, the CCO no longer checks for the nonexistent permission.

      Description of problem:

          The code requires the `s3:HeadObject` permission (https://github.com/openshift/cloud-credential-operator/blob/master/pkg/aws/utils.go#L57) but it doesn't exist. The AWS docs say the permission needed is `s3:ListBucket`: https://docs.aws.amazon.com/AmazonS3/latest/API/API_HeadBucket.html

      Version-Release number of selected component (if applicable):

          4.16

      How reproducible:

          always

      Steps to Reproduce:

          1. Try to install cluster with minimal permissions without s3:HeadBucket
          2.
          3.
          

      Actual results:

      level=warning msg=Action not allowed with tested creds action=iam:DeleteUserPolicy
      level=warning msg=Tested creds not able to perform all requested actions
      level=warning msg=Action not allowed with tested creds action=s3:HeadBucket
      level=warning msg=Tested creds not able to perform all requested actions
      level=fatal msg=failed to fetch Cluster: failed to fetch dependency of "Cluster": failed to generate asset "Platform Permissions Check": validate AWS credentials: AWS credentials cannot be used to either create new creds or use as-is
      Installer exit with code 1

      Expected results:

          Only `s3:ListBucket` should be checked.
