title: Define RabbitMQ policies in configuration file
body: <p>I'd like to define mirroring for all my queues by default. I currently have to <a href="https://www.rabbitmq.com/ha.html#examples" rel="noreferrer">use <code>rabbitmqctl</code></a> once the node is up:</p>
  <pre class="lang-sh prettyprint-override"><code>rabbitmqctl set_policy ha-all &quot;&quot; '{&quot;ha-mode&quot;:&quot;all&quot;}'
  </code></pre>
  <p>If one of my nodes fail, I'd have to remember to re-execute that code on restart.</p>
  <p>Is there a way to automatically configure my node to use mirrored queues?</p>
