Seems like something you could build based on consuming the notification 
RPC queue events in an external system. Most operations in nova have a 
start/end/error notification sequence. You can track when there are 
tasks running based on the start events, and when they finish based on 
the end/error events.

So, this is something you could build with what's available, as a 
separate optional dashboard thing. Not everything needs to be baked 
directly into a project as long as that project provides the APIs for 
consumers to build from it. Very similar concept with the zaqar thing 
that was discussed in the -tc channel yesterday.
