How to use

notifyOnUpdateProcessingListeners

method

   * (such as 45.1) and the next event delay is any integer number such as 5,
   * then the next simulation time will be 50.1.
   * At time 50.1 the utilization will be reduced due to the completion of the Cloudlet.
   * At time 50.0 the Cloudlet is still running, so there is some CPU utilization.
   * But since the next update will be only at time 50.1, the utilization
   * at time 50.0 won't be collected to enable knowing the exact time
   * before the utilization dropped.
