Would you look at adding some unit tests for st2.packs.configs? It is on this list of features that are missing unit tests: #28 (comment)

You can look at the other files under tests/unit/ to see how we've tested other features.

The tests will be a good way to show examples of how making the configs templatable could be used.

In particular I want to make sure something with a more complex template (maybe a range loop?) will render and get indented correctly. I wonder if we'll need to loop over each entry in .Valus.st2.packs.configs and template the contents of each file.
