title: Workaround for dash-ssh/click/python3 clash
body: <p>I am unable to run dask-ssh because of the click/python3 clash. I have LC_ALL and LANG set as recommended but click still objects. I recognise that this is a click/python3 problem but I hope that someone has seen and solved this.</p>
  
  <pre><code>$ env | grep LC_ALL
  LC_ALL=C.UTF-8
  $ env | grep LANG
  LANG=C.UTF-8
  $ dask-ssh localhost
  Your terminal does not properly support unicode text required by command    line
  utilities running Python 3.  This is commonly solved by specifying encoding
  environment variables, though exact solutions may depend on your system:
  
      $ export LC_ALL=C.UTF-8
      $ export LANG=C.UTF-8

  </code></pre>
  
  <p>Thanks,
