🚀Source Google Ads: Expand API Support

[sherifnada]

Tell us about the problem you're trying to solve

We want to support retrieving at least the following endpoints from the Google Ads API (not the deprecated google adwords API) :

• Campaigns
• Ads
• AdGroups
• Accounts

We also want to support Ads reports similar to the Google Adwords connector for Text, Shopping, and Display ads. This issue will require some scoping and research (following the standard template for product requirement scoping) before we can make progress.

Describe the solution you’d like

Describe the alternative you’ve considered or used

Google Adwords which is going to be deprecated in 9 months
