@Marvin What does the Foreman service do in Prefect 3

The Foreman service in Prefect 3 is responsible for managing and emitting work pool status events. It keeps track of the status of work pools and associated workers, marking them as ready or not ready based on their current state. Here are some key points about the Foreman service: - Work Pool Status: The Foreman service observes the state of work pools and workers and emits events when their readiness changes. For example, it marks workers and work pools as offline if they stop responding. - Deployment Status: It also deals with the persistence and events of deployment statuses. The service marks deployments as ready or not ready and updates the database accordingly. - Core Operations: Originally a part of Prefect Cloud, the Foreman loop is adapted to manage deployment states in Prefect 3.
