Corresponding lake PR: https://github.com/guardian/ophan-data-lake/pull/4423

Fix for why

thousands are in clean and not raw:*

SELECT approx_distinct(name) FROM clean.zuora_subscription WHERE name NOT IN (
    SELECT DISTINCT subscription_name FROM raw.zu_subs
) 

Having mutable fields in filter does not work with Zuora stateful export API so we have to add corresponding fields to export and filter them on the ophan-data-lake side.
