title: Ansible: set ssh arguments using group variables
body: <p>To connect to different groups of hosts, I need to use different ssh config files. I'm currently trying to connect to both groups in the same playbook, but I can't figure out how to change <code>ssh_args</code> within the playbook. I was wondering if I could use <code>group_vars</code> to do this?</p>
  
  <p>The way I currently set <code>ssh_args</code> is in <code>ansible.cfg</code>:</p>
  
  <pre><code>[ssh_connection]
  ssh_args = -F ./ssh.cfg
  </code></pre>
