Toon Claes ce830d3c60 Add Gitlab::Database::Subquery.self_join to delete_all with limit
`delete_all` doesn't support limit, so you'd need to subquery
that. And instead of subquerying with `where(id: query)`, it's better
to use an `INNER JOIN`. This method also works with MySQL, while
subquerying doesn't (without another layer of subquerying)
