      - Creates an app and all its workloads
      - Specify the templates for the app and workloads through `setup_app_templates` in the `.controlplane/controlplane.yml` file
      - This should only be used for temporary apps like review apps, never for persistent apps like production (to update workloads for those, use 'cpl apply-template' instead)
