Use Datadog monitors as quality gates for GitHub Actions deployments

The integration of Datadog with GitHub's Deployment Protection Rules allows users to create health checks for deployments and prevent faulty releases from affecting their entire system. This feature enables controlled releases by allowing users to stagger deployments and test functionality in isolated parts of the system before a wider release. Customized quality gates can be used to validate service health and resource consumption at every stage of deployments, helping assess the performance of new code under real conditions. Datadog's integration with GitHub Deployment Protection Rules provides notifications for passed and failed checks, allowing users to determine exactly where issues in their stack occurred and troubleshoot them before releasing across all environments.
