Adding metrics to alarm manager
Push atoms:
- Every time an alarm is scheduled, we push some attributes of the
alarm and the reason why such an alarm was allowed. This will help
audit spammy behavior from apps that misuse alarm API, e.g.
apps that have SCHEDULE_EXACT_ALARM.
- Every time an alarm batch is delivered, we log the size of the batch
and whether or not it was a wakeup batch. This is the essential measure
of alarm manager's batching efficiency.
Pulled atoms:
- Logging general stats on pending alarms every once in a while.
