nixos/gitlab: Make gitlab.service's PreStart into two new services
Make the config initialization script run in gitlab.service's PreStart section into two new services, `gitlab-config.service` and `gitlab-db-config.service`. Other services can then depend on the config scripts they need instead of unnecessarily depending on `gitlab.service`. This makes the reason for the configured service dependencies much clearer and should also reduce the restart time of the `gitlab` service quite a lot, when triggered manually. Also, set up stricter service dependencies, using `bindsTo`, to ensure that if a service fails or is stopped, its dependants are also stopped. For example, if we're using the `postgresql` service and it's stopped, `gitlab.service` and `gitlab-sidekiq.service`, which depend on it to function, should also be stopped.
