The Unifi controller consists of three containerized processes:
* Unifi Network itself
* unifi_exporter for monitoring and metrics via Prometheus
* Caddy for HTTPS
_unifi_exporter_ is really the only component with any configuration.
Unfortunately, it mixes secret and non-secret data in a single YAML
file, which makes it impossible to use `yaml.Marshal` to render the
configuration directly from the CUE source.
