Add CI markers
GitLab CI supports markers in the CI script. These in turn allow each section marked out to get its own time stamp. I'm figuring it can be useful just to get a feeling of what it is that takes time in a CI run. We can't do this too granularly but even high level I think it could help.
Right now I'm troubleshooting one installation. My gut feeling is that it is pushing to the registry that is really slow. Having markers would prove this.
