Submit (long running) Yarn Cluster via CLI w/out Client Script

Is there a way to use the CLI tools to submit a new YARN application and cluster, without creating a dask client script?

I know I can just add a while loop to the client script to run indefinitely, but it seems there should be a way to do something like:
```
dask-yarn start_cluster
```

I tried to just use `dask-yarn services scheduler/worker` but it complains about now being inside a YARN container:

```
