Code review comment for lp:~nuclearbob/utah/consolidate-scripts

I'd like to see different provisioning methods, whether those are functions or not, that basically only consist of getting the inventory and machine objects. Everything else I'd like to see handled the same way, either in run_utah_test.py or run.py. I'll work on cleaning up the documentation, and I think if we can land this proposal:

That'll put me in better shape to make the changes we've talked about in this branch.
