This module extends functionality of [google_projects](https://registry.terraform.io/providers/hashicorp/google/latest/docs/data-sources/projects) data source by retrieving all the projects and folders under a specific `parent` recursively.
A good usage pattern would be when we want all the projects under a specific folder (including nested subfolders) to be included into [VPC Service Controls](../vpc-sc/). Instead of manually maintaining the list of project numbers as an input to the `vpc-sc` module we can use that module to retrieve all the project numbers dynamically.
