Restore redirects from `gitlab-ci-multi-runner` to ` gitlab-runner` projects.

Recently we've moved the GitLab Runner project from https://gitlab.com/gitlab-org/gitlab-ci-multi-runner to https://gitlab.com/gitlab-org/gitlab-runner (gitlab-org/gitlab-runner#1195 (closed)). We've then recreated https://gitlab.com/gitlab-org/gitlab-ci-multi-runner with current master branch and previously existing images in Container Registry and marked the project as deprecated. However, this ended with a lot of links that are now returning 404.

After doing some investigation today we've realized that we (GitLab organization) are the only users of Runner's Registry. We've decided to remove the https://gitlab.com/gitlab-org/gitlab-ci-multi-runner project and restore the automatic redirect to new https://gitlab.com/gitlab-org/gitlab-runner project.

added requires production access label

To achieve that we need to:

• Remove/move https://gitlab.com/gitlab-org/gitlab-ci-multi-runner repository,
• Execute on rails/console the script below

RedirectRoute.find_by(path: "gitlab-org/gitlab-ci-multi-runner").destroy # this can fail
Route.find_by(path: "gitlab-org/gitlab-runner").create_redirect("gitlab-org/gitlab-ci-multi-runner")

Argh. I cannot remove container registry images for https://gitlab.com/gitlab-org/gitlab-ci-multi-runner.

Tags are removed.

This is done. Thanks @omame.
