Currently, the SingleOwnNamespace OTE tests don't run on disconnected environments. This signal is required for us to be able to flip the feature to GA in openshift/api. While a broader solution to the problem of disconnected environment tests are needed, to unblock the feature promotion we update our tests to follow the fixture image building process used in the olmv1_incompatible tests and build our own catalog and bundle images for the tests. As in olmv1_incompatible, use image.ShellImage() provided by the origin library as the controller image for the test operator. The fixtures bundles will just need to define their own CSV with the appropriate install mode support, for instance, like in the test-operator bundle we have upstream: https://github.com/operator-framework/operator-controller/blob/main/testdata/images/bundles/test-operator/v1.0.0/manifests/testoperator.clusterserviceversion.yaml#L132
