[Feature] Add disabling models for non-existent sources about dbt_snapchat_ads_source

[fivetran-joemarkiewicz]

Hi @kirkbrunson-dave thanks so much for opening this ticket and my apologies that it has taken our team longer than expected to look into this ticket.

I believe this is a doable feature request and I could see others benefiting from the ability to disable the url tag source if they are not using it. In addition to disabling the models within the staging package, we would also want to disable its downstream uses. It seems the main use is within our creative prep intermediate model. Disabling the linked CTE shouldn't be too much of a lift or cause issues for others.

Our team will scope this out further and plan to bring the update into a future sprint. We will post back here with more details once we start working on the feature.
