Want to see if we can get a more abstract version of
## Run tests in docker container
docker/test:
docker run --name terratest --rm -it -e GITHUB_TOKEN \
-e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN -e AWS_ENDPOINT_URL \
-e PATH="/usr/local/terraform/bin:/go/bin:/usr/local/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" \
-v $(CURDIR)/../../:/module/ cloudposse/test-harness:latest -C /module/test/src test
in the build (or test?) harness (and some other magic here as well).
What would be the best place to add it? as it involves docker, aws and terraform
