title: specify exact cookbook version in node run_list still possible?
body: <p>I have this in my notes that <code>{"run_list":["recipe[nginx@1.2.3]"]}</code> is possible to explicitly specify a cookbook version to use in a nodes run_list but i can't get it to work and can't find any documentation to say if this is still supported or if it's been deprecated. </p>
  
  <p>This is using chef 11.18.0. Can anyone confirm if this is still OK to use and where this should be configured. In the node run_list or role run_list ?</p>
  
  <p>thanks</p>
