Filter index of subscriptions by deleted

Will request all active and only deleted subs that
were done within past 90 days.

closes PLAT-4945

Test Plan:
 - test this with commit https://gerrit.instructure.com/211181
 - Ensure you have at least one sub that is deleted over 90
   days ago (edit ddb if needed)
 - See that the index does not show that sub
