Right now, when the namespace is not specified in the policy, it will default to "openshift-operators" (as long as the cluster is an OpenShift cluster).

But many operators specify other namespaces, which the OpenShift UI suggests to the user when they are installing the operator. We should match that behavior.

The information is available in the Package Manifest, at status>channels[]>currentCSVDesc>annotations>"operatorframework.io/suggested-namespace"
