Part 1: properly pin operator image in bundle midstream.

Use image pinning (https://docs.engineering.redhat.com/display/CFC/Digest_Pinning ) to allow that the operator image referenced from the operator-bundle is registry-proxy... before the proxy is released and in the public release is automatically set to registry.redhat.io...

Part 2: properly pin operand images.

From "Best Practices" document https://docs.engineering.redhat.com/display/CFC/Best_Practices :

Images to be used for operands MUST be in the relatedImages field and SHOULD be in environment variables to the operator.

I'll check how we can change this so we can get it for GA. I'll add  JIRA issue to track the progress on that.
Then QE can test them according to this document: https://docs.engineering.redhat.com/display/CFC/Test

Check e.g. how external dns resolver resolves the operand images: https://gitlab.cee.redhat.com/cpaas-midstream/external-dns-operator/-/blob/ext-dns-optr-1.0-rhel-8/distgit/containers/external-dns-operator-bundle/render_templates
