Application deployments inhibits periodic redeploys for a while

Why?
1) Too many redeploys are unecessary and have a cost
2) If restartOnDeploy is turned on, we may end up not able to
   respect it to make sure config is actually deployed if a periodic
   redeploy follows right after an application deploy.
