      Description

      Yarn should provide some way to figure out if yarn service is destroyed.

      If yarn service application is stopped, "yarn app -status <appname>" shows that service is Stopped.

      After destroying yarn service, "yarn app -status <appname>" returns 404

      Yarn should be able to notify user that whether a certain app is destroyed or never created. HTTP 404 error does not explicitly provide information.
