> To improve the debugging of scheduler issues it would be a big improvement to be able
to dump the scheduler state into a log on request. 
> The Dump the scheduler state at a point in time would allow debugging of a scheduler
that is not hung (deadlocked) but also not assigning containers. Currently we do not have
a proper overview of what state the scheduler and the queues are in and we have to make assumptions
or guess
> The scheduler and queue state needed would include (not exhaustive):
> - instantaneous and steady fair share (app / queue)
> - AM share and resources
> - weight
> - app demand
> - application run state (runnable/non runnable)
> - last time at fair/min share
