Usage of Message Queue Based Notification inside VidiFlow Components for Configuration Updates [VF 20.2 RN]

All components (services and agents) in VidiFlow now use the internal notification service for configuration updates. Prior to this, these were listened directly to SignalR messages from ConfigPortal.
Additionally, ConfigPortal can now also send a notification directly to the internal notification service via RabbitMQ queue. Thus, the internal VidiFlow notification service gets notifications for configuration changes via the message queue and forwards those changes to affected VidiFlow components again via message queue. The usage of unreliable SignalR notifications is now obsolete for VidiFlow.
Other applications which have no message bus may still subscribe to SignalR messages from ConfigPortal.
