Manage flow runtimes

The execution environment for flows is accomplished in a Flow runtime. It can be installed as a single Docker container or as a Windows service. A flow runtime can run multiple flows and those flows can be updated and added without restarting the container or service and without affecting other flows.

The flow runtime serves an integrated MQTT Broker that covers publishing and subscribing communication patterns. The node also has a built in HTTP-Server and supports full-duplex communication over WebSockets.
