3. ENV var interpolation for the config files

I’m often running these singer workloads in containers. It’s quite a painful dance to pass environment variables to the singer config files. Why not provide first-class support for env vars via 

{{ MY_ENV_VAR }}

 in the config files? (edited)

Are you using Meltano for orchestration? Meltano gives you several options, such as dotenv files, local env vars on the machine, or using the internal meltano system db. Is that similar to what you are looking for, or if not, can you say a bit more?
