Update Network Operator to pull images from this repository

[Eoghan1232]

This was mentioned before during the previous release.

Right now it uses images built on quay openshift repo https://github.com/openshift/sriov-network-operator:

sriov-network-operator/hack/env.sh

Line 7 in b876ce5

CNI_IMAGE_DIGEST=$(skopeo inspect docker://quay.io/openshift/origin-sriov-cni | jq --raw-output '.Digest')

Shouldn't those envs be changed to values from here to use images built from this repository?

Makefile uses hack/deploy-setup.sh which builds the operator

Had an issue where I had to manually set the tags in the env.sh file, in order for my deployment to work, as a latest version of Network Operator/Device Plugin that was being pulled from quay.io was breaking for me.
