Feature: Union schema compatibility

[fivetran-catfritz]

Issue: #27

Confirm the following files were correctly updated automatically:

• CHANGELOG
• README
• stg_facebook_ads.yml, src_facebook_ads.yml, facebook_ads.yml (depending if source or transform)
• docs.md
• joins
• window functions (partition by)
• 'source_relation' column added in staging and transform models
• tests

Manual updates:

• Add source_relation to downstream models if necessary
• Finish any incomplete/incorrect joins/partitions
• Update tests to include source_relation in unique-combination-of-cols if necessary
  • May need to remove some uniqueness tests in favor of the combo test

Validation:

• dbt run locally passes
• dbt test locally passes

@fivetran-catfritz these changes are looking great! However, I would like us to try and modify the package so we may avoid needing to update fivetran_utils. Would you be able to explore those updates and apply/document them if possible. Other than that, I just have a few additional notes.

@fivetran-catfritz this is looking great! I just have a clarifying question if the actual schema and database variables needed to be changed? I don't think they do, but curious if you found a reason why they would need to be updated.

I mainly ask because this is a pretty large breaking change. It is appropriate that this will already be included with other breaking changes, but if we could avoid this one then that would be ideal. This way it makes the upgrade that much smoother.

Thanks for making these updates! This looks good to go @fivetran-catfritz 🏅
