This roster resolves hostname in a pdsh/clustershell style.
:depends: clustershell, https://github.com/cea-hpc/clustershell
When you want to use host globs for target matching, use ``--roster clustershell``. For example:
.. code-block:: bash
salt-ssh --roster clustershell 'server_[1-10,21-30],test_server[5,7,9]' test.ping
