Loading `Geo::ContainerRepositoryRegistry` requires a Geo secondary database
After https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/3809, booting Rails (running any spec / opening Rails console) fails without a Geo secondary setup.
We added Geo::ContainerRepositoryRegistry and this model uses state_machine. This causes some queries to run when the class is loaded and this fails because this model requires a Geo secondary.
