(QA-3110) spike: rototiller create integration suite

* implement an integration test helper set
  * this creates a helper that can run a single task in rspec
* we could create another helper for rake -T and rake -D, etc, maybe
  * or it might make sense to just keep testing that stuff in acceptance
* this doesn't work
  * it appears to not run the commands, not clear why
