This adds the min_client_version decorator to be used in the CLI tests. The decorator is used skip CLI tests where the command being tested isn't available in the version of the client we're testing against. The cmd method is pulled out of the ClientTestBase class so it can be used by the decorator and is renamed so it does not conflict with the cmd argument passed to it. To start using the decorator and show how it works, two known CLI tests are decorated for minimum version checks on their clients.
