Hi all, is it possible to override an arbitrary property using an environment variable? For example in yaml I have `postgres.database: my-db` that I'd want to override with an env var `POSTGRES_DATABASE: my-real-db`. I know I can do `postgres.database: "$POSTGRES_DATABASE:my-db"` but that seems like a lot of noise for every possible property.

Similarly to what Spring does: <https://docs.spring.io/spring-boot/reference/features/external-config.html#features.external-config.typesafe-configuration-properties.relaxed-binding.environment-variables|https://docs.spring.io/spring-boot/reference/features/external-config.html#features.external-config.typesafe-c[…]laxed-binding.environment-variables>

Unfortunately, Ktor does not have such functionality (using environment variables based on the properties' names). You can file a <https://youtrack.jetbrains.com/newIssue?project=KTOR|feature request>.
