Environment variables for secrets

[devotee101]

Might be a feature request, but is there any way of using environment variables for the secure information in the config.yml, i.e. the MQTT password and udl_password?

FYI, I'm running in k8s so I'd like to secure that data using Secrets.

Worked around it for the time being by storing the entire config in a Secret rather than the ConfigMap I was using. It'd still be nice to override the secure parts of config via environment variables, if that can be added at some point in the future?
