Feature: Union schema compatibility

[fivetran-catfritz]

Issue: #34

Confirm the following files were correctly updated automatically:

• CHANGELOG
• README
• stg_google_ads.yml, src_google_ads.yml, google_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
• See internal ticket for the validation that tests multiple sources

These updates look great! I have just a small request to update the CHANGELOG and README. Once those are updated, this will be good to go after the remaining package updates are approved.
