These new settings files are intended to be used by the Analytics
Exporter automation managed by the DE team. The Analytics Exporter must
be able to simply clone edx-platform, install requirements, fetch
remote-config, then just run management commands without needing to run
any ansible or pull down any docker/AMI images. Since the theming app
includes a check that fails if the themes base dir cannot be found, and
that check runs on app startup, we must disable the app.
