VPC Service Controls feature (Status: Preview): Support for optimizing service

## Feature Feature **VPC Service Controls feature (Status: [Preview](https://cloud.google.com/products#product-launch-stages)):** Support for optimizing service perimeters using the VPC Service Controls recommender is available. The recommender detects architectural risks and perimeter misconfigurations, including the following: * **Critical resources at risk of exfiltration**: Identifies active and sensitive services (such as BigQuery and Cloud Storage) operating outside service perimeters. * **Unconfigured VPC accessible services**: Identifies perimeters that leave APIs unrestricted from within the security boundary. * **Misconfigured VPC accessible services**: Identifies mismatches between allowed accessible APIs and restricted services inside a perimeter.
