The ability to allow *.config files to use enviroment variables would enourmosly help docker deployments.

Let's use a real config as example, for example JournalDDMEditorConfiguration

To set the value for that configuration i would have to create the bundle with

useDataEngineEditor=true

already set or i would have to rely on something inside my container that could change that value later.

If we could have something like:

useDataEngineEditor=${someEnvVar}

that would be extremally valuable and would provide us a great flexibility when working with containers.
