Starting November 1st Docker Hub will rate limit anonymous pulls of docker images (100 pulls/day). This affects our CI pipelines, since they all run from shared CircleCI servers.

CircleCI's suggestion is that we authenticate, so we don't get affected by the rate limit.

This has been done already on all p4 application repos, but also on NRO deployment repos (example). But we need to check also all CI/Infra repos, where we use Docker Hub to pull images.
