title: Drools logging with logback
body: <p>I'm using Drools 5.4.0.Final
  For logging I'm using logback in my application.</p>
  
  <p>I tried to add update my logback.xml with</p>
  
  <pre><code>&lt;logger name="org.drools" level="debug"/&gt;
  </code></pre>
  
  <p>But I see nothing in my logs concerning Drools.
  I would expect to see so my lines of logs concerning the drools initialization.</p>
