Bug Description

I'm not sure if this is a bug or if it has not been implemented, I was trying to do something like the dependent environment variables from k8s, but using config connector, however it does not seem to work, I tried doing exactly as k8s exemplifies by setting a variable hardcoded and trying using it on the next variable, however the variable is not expanded.

Additional Diagnostic Information

Expected the variable to be expanded, for example:

env:
  - name: VAL1
    value: World
  - name: VAL2
    value: "Hello, $(VAL1)"

Logging that on the application pushed to production gives the following output: INFO [18:29:56.093] [DefaultDispatcher-worker-1] com.trash.svcs.tracker.TrackerEndpoint - Hello, $(VAL1)

Expected: INFO [18:29:56.093] [DefaultDispatcher-worker-1] com.trash.svcs.tracker.TrackerEndpoint - Hello, World

Steps to reproduce the issue

Set 2 variables, the first with some arbitrary text, and try to use its value on the next variable, I think it will be easier to understante looking at the yaml snippet provided ahead.
