This improves one of our gTech processes so they no longer have to remember to create Google Groups for a registrar after creating that registrar. The ConfirmingCommand.verify() method is renamed to be more general purpose, so that it can do anything that follows naturally after a successful execution, such as creating Google Groups groups. Minor refactoring is done around RegistryToolEnvironment handling for tests to make it more bullet-proof and general case. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=117494277
