title: Chef: Delete node with knife and add it again later
body: <p>Say do a <code>knife node delete 'NODENAME'</code> to delete the node from chef server while leaving the corresponding VM running like it is.</p>
  
  <p>Is it possible, if I need to make changes to that server in the future, to add the VM again as a node and run chef-client on it (or any other chef command for that matter)?</p>
