The values are nonsensical but this should be a fairly complete collection
of settings, both at the top level and in sub-dictionaries.
While edxapp will not work properly with these settings, the following
commands should work:
```
DJANGO_SETTINGS_MODULE=lms.envs.production LMS_CFG=lms/envs/mock.yml ./manage.py lms dump_settings
DJANGO_SETTINGS_MODULE=cms.envs.production CMS_CFG=cms/envs/mock.yml ./manage.py cms dump_settings
```
