title: Cloudify restart livecycle event
body: <p>I'm writing a cloudify recipe  and I am trying to manage the HA. In the cloudify doc, i saw the following concerning the "stopDetection" probe:</p>
  
  <blockquote>
    <p>It is important to note that Cloudify will invoke the <strong>restart</strong> event if
    you implemented one and the <strong>start</strong> event will only serve as a fallback.</p>
  </blockquote>
  
  <p>Does it means that cloudify has a "restart" lifecycle event (such as start, stop)?</p>
  
  <p>Thanks.</p>
