title: Deltaspike and Quartz: How to set cronExpressions from a config file
body: <p>I guess the title is quite self-explained. I have a job:</p>
  
  <pre><code>import org.apache.deltaspike.scheduler.api.Scheduled;
  import org.quartz.Job;
  
  @Scheduled(cronExpression = "0 0/1 * * * ?")
  public class JobA implements Job {
    //job code
  }
  </code></pre>
  
  <p>harcoded to run every minute. I would like to set that cron expression from outside, i.e. a config file.
  I'm using Deltaspike, I can't find a way to achieve it. I was thinking of a class JobDispatcher maybe, from where to create the job and set the cron expression to it, but I see no clue in DeltaSpike documentation</p>
  
  <p>Thanks in advance!</p>
