### Resource Groups Tagging API
GoLang SDK Docs: https://docs.aws.amazon.com/sdk-for-go/api/service/resourcegroupstaggingapi/
The package resourcegroupstaggingapi provides the client and types for making API requests to AWS Resource Groups Tagging API.

This example was written especially for GoLang newcomers (like me).

Scenario: Getting all resources ARNs which are tagged with "APP_NAME = api-group"
Given: There are two resources that are tagged with "APP_NAME=api-group", both are S3 buckets
