Consolidate test bundle and example bundle

The test bundle had a lot of great edge cases and examples for how to use terraform in a bundle that would be useful to make people aware of in our example bundle. I have updated the basic-tf-example bundle with the contents of our test bundle. I also added defaults for all the parameters so that it doesn't require any additional config to run.

This is also good because our example bundle is tested in CI now.
