Remove GitLab CI from run list for 8.0

Since GitLab CI coordinator is being migrated to GitLab app:

When upgrading by installing the 8.0 package:

1. Remove GitLab CI related recipes from the runlist
2. Remove GitLab CI cron job
3. Stop any running GitLab CI services
4. Replace existing CI nginx template with the redirect config. Populate using existing data + allow configuration for DNS resolver.
5. secrets.yaml for gitlab-rails

Clean up of GitLab CI from the code should happen in later release => #792 (closed)
