title: Openshift cron on scaled application
body: <p>I have an openshift application which runs a cron cartridge. I changed it recently to become a scaled app only to realize that the cron will fire on all scaled versions of the app aswell. This messes up my database pretty badly.</p>
  
  <p>Is there any easy way to make the cron tasks only fire once? Tried googling around but found no answer sadly..</p>
