The Zendesk connector has a lot of "core" tables under the ticket table that cannot be blocked and cause a large increase in MAR.

In particular ticket_alert and alert_recipient and ticket_tag.

We don't always need these tables and they shouldn't be core because they aren't mandatory in other ETL tools. At this stage the MAR increase is a deal breaker for Fivetran so we'll need to use a different ETL service.

Can those tables be made non-core so we can deselect them?
