title: Vert.x - Get deployment ID within currently running verticle
body: <p>I'm looking for the deployment ID for the currently running verticle.</p>
  
  <p>The goal is to allow a verticle to undeploy itself. I currently pass the deploymentID into the deployed verticle over the event bus to accomplish this, but would prefer some direct means of access.</p>
