ASCENT download of terraform should be a git repo

Currently we allow users to download a tz file containing all of the automation. That tz should also include the git metadata (e.g. have a .git folder created by running something like `git init` and `git add . && git commit -m "Initial commit"`)

That way the user can start making versioned changes to the content and/or push the content quickly to a remote by running `git remote add origin xxx` and `git push`
