Checks for tasks that are having frontier failures from MWT2 Elastic Search repository. Elastic Search queries
based on Ilija Vukotic scripts here: https://github.com/ATLAS-Analytics/AlarmAndAlertService/blob/master/frontier-failed-q.py

These tasks are getting reassigned to a separate, throttled global-share with Frontier heavy tasks. Exceptions that
will not be reassigned are:
 - jobs that don't belong to any task (usually HammerCloud test jobs)
 - analysis tasks, since there has not been any unification yet
