title: Dask restart worker(s) using client
body: <p>Is there a way using dask client to restart a worker or worker list provided. Needed a way to bounce a worker after a task is executed to reset the state of the process which may have been changed by the execution.</p>
  
  <p>Client.restart() restarts entire grid and so may end up killing any tasks running in parallel to one that just completed.</p>
