The decision engine process was built based on 2 services: a service that handle rpc requests and a scheduler to trigger watcher periodic tasks. With the new version of oslo.service, a new threading backend was added, based on cotyledon service manager, which starts a new process for each service tha it manages. These two services can't run in different process since they need access to a shared in-memory representation of the cluster (cluster data models) This patch proposes creating a Decision Engine Service which includes everything in a single main service.
