Move kube-rbac-proxy image into GitLab Container Registry
Summary
A customer has reported that their cluster can reach out to the GitLab Container Registry at registry.gitlab.com but not to grc.io. So downloading gitlab-operator image isn't a problem. But their cluster is not allowed to go to grc.io, which is where it pulls the kube-rbac-proxy image from.
This image is hardcoded into the deployment here.
Are we able to proxy this image from the GitLab Container Registry instead?
We have recently done the same in the GitLab Runner Operator repository. Not sure if it's possible to use the same image URL, otherwise I would have created an MR.
