oc new-app doesn't honor local docker configuration

Issue

• oc new-app command doesn't honor docker configuration regarding registries. The OCP cluster points to an external Red Hat standalone Registry. And the Docker daemon is configured that way, to point to the external Registry where the docker configuration is as below :

BLOCK_REGISTRY='--block-registry registry.access.redhat.com --block-registry docker.io'

However the new-app command still goes to docker.io:

#oc new-app openshift/hello-openshift:latest
W0818 10:50:40.891868   81558 dockerimagelookup.go:220] Docker registry lookup failed: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
error: no match for "openshift/hello-openshift:latest"
