Introducing Prometheus support for Datadog Agent 6

The latest version of Datadog's Agent now supports Prometheus metrics through the OpenMetric exposition format. This integration allows users to monitor Prometheus metrics alongside other data collected by Datadog's built-in integrations and custom instrumentation libraries. Users can configure the Datadog Agent to scrape available endpoints for exposed metrics, visualize their data in comprehensive graphs and dashboards, and create custom checks for additional control over metric collection. This integration also works seamlessly with Kubernetes components that expose metrics via the OpenMetrics exposition format, such as CoreDNS and kube-dns, and supports Datadog's Autodiscovery feature to automate the collection of Prometheus metrics in a cluster.
