operators/v1alpha1: expose CSV copied logic (#289)

We want to use a partial object metadata query for CSVs to reduce
resource utilization. We still want to ask questions about whether these
CSVs are copied, so we need to refactor this method to take only object
metadata. While it's not a perfect port of the previous logic, it defies
explanation how an object would have all the other markings of being
copied but the wrong status.
