event database will grow gradually, currently, even though we can dump data to 3rd storage, the old data cannot be cleaned. This patch adds a new option [database].event_time_to_live, and create ttl index on event collection for MongoDB backend. Also change previous [database].time_to_live to precise [database].metering_time_to_live. To enable test_bin, this patch also simply implements log:// partially implements blueprint event-database-ttl DocImpact Change-Id: I0d67cf212f37d3fa5555870a8e7cbb65af205d63
