title: Have ansible playbook wait until host is active
body: <p>I am looking to run a playbook that checks if a host is active, and if not check again in 24 hours. </p>
  
  <pre><code>start playbook
  
      do while host X is not up
      {
          wait 24 hours
      }
  </code></pre>
  
  <p>Is this possible in ansible? From the docs, it's very unclear if it is.</p>
