Docker Inc is rolling out new [terms of
service](https://www.docker.com/pricing/resource-consumption-updates)
which will introduce rate limits on `docker pull` from DockerHub for
anonymous users.

Users can already set a DockerHub mirror to not reach these limits
when running CI jobs using the Docker executor. However when they use
the `dind` service to build their images this won't use the registry
mirror because it needs to be explicitly configured for the daemon.
