Research direction

The issue only provides a link to Prometheus, lacking specific requirements. To start, examine Cabot's existing alert backends (e.g., in the `cabot/alert/` directory) to understand the integration pattern. Then, review the 4 comments on the issue for any prior discussion or decisions. Finally, propose a detailed implementation plan in a new comment, including which Prometheus features to support and how to integrate with Cabot's existing alerting models.
