Subject: [PATCH] Bug 19008: More database cleanups - statistics

misc/cronjobs/cleanup_database.pl provides some database cleanup.
Yet some tables that could need cleanup are not in this script.

This patch adds cleanup for statistics table.

Test plan :
- Count statistics : select count(*),date(datetime) from statistics group by date(datetime);
- Run cleanup : misc/cronjobs/cleanup_database.pl -v --statistics 30
- Recount statistics
