 Deploy the 4.6 ptp operator following the new procedure.
 
 1. Get the 4.6 index image by https://mastern-jenkins-csb-openshift-qe.cloud.paas.psi.redhat.com/job/mirror_to_image_bundle_to_qe_registry/
 2. Create ICSP
 
$cat <<EOF  | oc create -f -
apiVersion: operator.openshift.io/v1alpha1
kind: ImageContentSourcePolicy
metadata:
  name: olmcontentsourcepolicy
spec:
  repositoryDigestMirrors:
  - mirrors:
    - quay.io/openshift-qe-optional-operators/
    source: registry.redhat.io/openshift4/
EOF
3. Create CatalogSource
#!/bin/bash
QE_index_image="quay.io/openshift-qe-optional-operators/ocp4-index:latest"
cat <<EOF | oc create -f -
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
