anagainaru/SchedulerSimulator: ScheduleFlow

Changes since v.1

Updates the scheduling algorithms

• New algorithm for priority based schedulers (multiple priority queues, easyBF between the same priority, conservative otherwise)
• Remove online scheduler since it can be simulated from the batch scheduler

Updates to the utils

• New JPG printing format (for high number of jobs)
• Added the option to extract the stats and plot the GIF and JPG for an external schedule log (e.g. if the user wants to merge multiple schedules from sequential simulations)
• Options to run multiple iterations (starting from a previous state with different DiscardPolicy options)
  • Either keep all the jobs that did not finish in the previous iteration, discard all jobs or only keep the high priority ones

Bug fixes:

• Computing the schedule gaps (when fitting jobs at the end of the schedule)
• Remove deprecated functions used to generate the gif
• Fix bug in the GIF vertical ax label

API changes

• Scheduler object is the only type of scheduler available (OnlineScheduler and BatchSchedulers are not separate anymore, this can be achieved through parameters to the Scheduler class)
• The scheduler can now receive an option generate_jpg that generates the JPG image with the final schedule
