Integration test

[zhilingc]

More or less done, making the PR first. Added integration test that runs the following steps on argo:

1. build cli
2. provision infra with TF
3. run pytest which:
   a. registers necessary specs
   b. runs job
   c. checks the output against expected values

currently the repository is pointing to my fork, will change over to the main repository when the changes are complete

Can you add a short Integration Tests section to the testing/readme that describes the whole sequence in english?

And a part that points to where we should start if we want to add new integration tests?

I've added some readmes but I'm in the process of figuring out a way of easily extending what's already there... any ideas?
