Allow templating of st2.packs.configs in values.yaml

As it says on the tin.

Allows the use of go templating in the st2.packs.configs value when creating the Configs ConfigMap

Fascinating. Do you have any examples of how you would use this?

Would you look at adding some unit tests for st2.packs.configs? It is on this list of features that are missing unit tests: https://github.com/StackStorm/stackstorm-k8s/issues/28#issuecomment-1048530740

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.

I can take a stab at it - but could we get https://github.com/StackStorm/stackstorm-k8s/pull/417 reviewed and merged first so I don't have to write the tests twice ;)
