Each test in the atomic-host-tests/tests directory has a "main" file (this is downloaded as part of the task). Some of the tests have a "yml" extension and others have a ".yaml" extension (which is what this task looks for).
Make this task more robust so it'll determine which is present and run that instead of failing when it can't find "main.yaml".
