Code review comment for lp:~utah/utah/bug1039555

The run_utah_tests documentation could do with some explaining on how it uses the other scripts.

The utah document needs a bit more of description, explicitely saying that is only intended to be used for development purposes or when the machine targetted for the testing is the current development machine, that otherwise it'll be used by run_utah_tests after provisioning the test environment.

Other than that I like the documents a lot, please make sure to explain max and joe how to keep them up to date.
