Command to view all events in system

[berndtj]

Bug Report

Getting a view of events which are subscribable is currently hard. We rely on documentation in event drivers to give a comprehensive and accurate list of event types and source formats. This is prone to error and is a pain for developers. It would be nice to have an API/CLI which can list the current events in the queue/being emitted.
