Added cron to prune events older than 12 months. Since contribution calendar shows only 12 months of activity, events older than that time are not visible anywhere and can be safely pruned saving big amount of database storage. Fixes #21164 2016-09-05 08:18:08 +00:00			`class PruneOldEventsWorker`

Limited amount of pruned Event rows per run Old deployments of Gitlab might have a big number of old events to be deleted. Such numbers cause the worker to timeout. I've limited the amount of rows that should be destroyed at once to 10000, and increased how often pruning shall take place to 4 times a day. 2016-09-05 20:57:56 +00:00			`Event.delete(Event.unscoped.where('created_at < ?', (12.months + 1.day).ago).limit(10_000).pluck(:id))`
