Throttle how frequently delay alarms are set.

If there are many timing delays set within a few milliseconds of each
other, TimeController can end up spamming and overwhelming AlarmManager.
Since a job doesn't need to have its delay constraint updated
immediately and we therefore don't need to have exact timing of every
single delay alarm, we should be alright limiting how often a delay
alarm can be set to go off.
