Right, I'm think now we should create a new set of variables 

```
lms_service_variant_enabled:  false
lms_xml_service_variant_enabled: false
cms_service_variant_enabled: false
lms_preview_service_variant_enabled: false
```

And change make env and auth hashes default to an empty hash again.
This way we can put examples in secure_example directory without enabling the services.
