Every time

1. Create an installer policy with the permissions listed in the installer [here|https://github.com/openshift/installer/blob/master/pkg/asset/installconfig/aws/permissions.go]

The installer log should show AccessDenied messages for the IAM action elasticloadbalancing:SetSecurityGroups 

The installer should show the error message "failed to apply security groups to load balancer"

Managed OpenShift (ROSA) installs STS clusters with [this|https://github.com/openshift/managed-cluster-config/blob/master/resources/sts/4.16/sts_installer_permission_policy.json] permission policy for the installer which should be what is required from the installer [policy|https://github.com/openshift/installer/blob/master/pkg/asset/installconfig/aws/permissions.go] plus permissions needed for OCM to do pre install validation.
