Openshift having issues installing certificates for corporate Docker registry

Issue

• When having an internal docker registry for disconnected deployments, the registry has a self-signed cert, but that cert is in the PKI store on every openshift node. In 3.9.x, i am able to 'oc import-image' without having to '--insecure', however in 3.10.x it's failing x509. It looks like openshift is not using my system-level PKI store to import these images.

[root@master01 ~]# oc import-image repo.home.example.com/rhel7.5 --confirm -n openshift
The import completed with errors.
