title: Vertx default configuration file
body: <p>is there a way how to make vertx load specified default configuration without doing:  </p>
  
  <pre><code>java -jar my-fat.jar -conf /path/to/my/conf.json
  </code></pre>
  
  <p>I mean to make vertx use config file which is present in that <code>my-fat.jar</code>.</p>
  
  <p>For simplicity I would like to have one config by default - maybe could be overriden from outside or maybe not for now. I have lot of microservices that runs independently and separately and I would like to produce them as jars, that are self sufficient.</p>
  
  <p>Can this be done programmatically or maybe with maven?  <br />
  Thanks for help.</p>
