Issue argoproj#6: Argo CLI features and improvements:

- `argo app list` to display running apps
- `argo app show <appname>` to display details about an app
- `argo job logs <service_id>` to retrieve logs for container in a job
- `argo job show --tree` improvements to be able to distinguish parallel vs. sequential steps in a workflow
