Status monitoring display
We should have some sort of display that interacts with artdaq and collects information about the state of the system (via metrics, request messages, routing tables, etc), and creates live, easy-to-understand displays outlining the health of the system.
For BoardReaders, this display should track things like the data buffer size, the Routing Table size, and the number of outstanding requests or the current Sequence ID.
For EventBuilders, this should track the state of the buffers, the art process event-uptake time, and the number of events routed to that EB.
DataLoggers and Dispatchers would have similar things to the EventBuilder.
