Need some way of deploying test_data even if they are included in .gitignore

[azdlowry]

We have some test certificates that are encrypted when stored in git and the build processes uses a local key to decrypt them. To ensure that we don't accidentally check in the un-encrypted versions they are included in .gitignore which also means they don't get deployed into the bundle. However we need these files for the tests to run.

I'm looking at fixing this myself, but not sure on what the best approach would be. Maybe adding an option to the test_data to ignore .gitignore?
