title: kitchen synced_folders owner and group
body: <p>I am trying to spin a chef cookbook with kitchen converge. I have synced_folders set up which are created correctly, however I can not assign the desired USER:GROUP. There is no kitchen documentation on how to do it and I have tried different ways which either generates error or gets ignored. 
  I have been able to do so without any issue on Vagrantfile and this is the way it is handles on Vagrant:</p>
  
  <pre><code>myvm.vm.synced_folder "~/Workspace/test", "/opt/apps/test/synced", owner: "www", group: "www"
  </code></pre>
  
  <p>here is how I have tried to achieve the same thing using kitchen but as I stated it only creates the folder with default user(vagrant)</p>
  
  <pre><code>suites:
    - name: myvm
      driver:
        vm_hostname: myvm.kitchen.verifi
        network:
          - ["private_network", {ip: "192.168.50.14"}]
        synced_folders:
          - ["~/Workspace/test", "/opt/apps/test/synced", "create: true", "owner: www-data", "group: www-data"]
  </code></pre>
  
  <p>the above only creates the folder
  changing it to :</p>
  
  <pre><code>  synced_folders:
      - ["~/Workspace/test", "/opt/apps/test/synced", "create: true", "owner: www-data group: www-data"]
  </code></pre>
  
  <p>was basically the same, the owner and groups get ignored</p>
  
  <p>changing it to :</p>
  
  <pre><code>  synced_folders:
      - ["~/Workspace/test", "/opt/apps/test/synced", "create: true owner: www-data group: www-data"]
  </code></pre>
  
  <p>generates error.
  No matter what combinations I use it does not succeed.</p>
