Bug 1769003

Thanks for the suggestion. OLM is an independent project as part of the Operator Framework, not Origin. We'll continue to use the Operator SDK to generate the CRDs and should have structural CRDs (as required in 1.16) soon.

The best option is the check the CRDs status, but the most important part is to have pruning enabled,
you do that setting 

preserveUnknownFields: false

like here: https://github.com/openshift/api/blob/master/operator/v1/0000_20_kube-apiserver-operator_01_config.crd.yaml#L11

this will enforce structural schema to start with. Now you'll need to ensure that the rest of your CRD 
follows it. It's best to create your CRD and check its status, if there will be problems you should see
that reflected in CRD's status.

Cluster version is 4.4.0-0.nightly-2020-02-23-191320
mac:~ jianzhang$ oc exec catalog-operator-6f68c78746-lgfwf -- olm --version
OLM version: 0.14.2
git commit: 3d7f04faecb0072e72858b67af34232f854a17cc

Now, the apiVersion of the CRD is `v1`, the pruning enabled as default.
Check the CRD created by OLM:
mac:~ jianzhang$ oc get crd |grep operators.coreos.com 
catalogsourceconfigs.operators.coreos.com                   2020-02-24T03:28:28Z
catalogsources.operators.coreos.com                         2020-02-24T03:28:37Z
clusterserviceversions.operators.coreos.com                 2020-02-24T03:28:35Z
installplans.operators.coreos.com                           2020-02-24T03:28:36Z
operatorgroups.operators.coreos.com                         2020-02-24T03:28:38Z
operatorsources.operators.coreos.com                        2020-02-24T03:28:31Z
subscriptions.operators.coreos.com                          2020-02-24T03:28:37Z

Check the status of all of them, works well. LGTM, verify it.
