> need to determine how much to send:
>  - dag termination cause
>  - vertex termination cause
>  - all tasks termination cause
> Perhaps logic such as 
>  - dont send task termination cause (too much volume with high noise ratio)
>  - however, any Vertex with VertexTerminationCause=OWN_TASK_FAILURE could failingTaskCount and a single failed-task-ID to aid post-mortem.  (it is probably interesting to user if few task of many failed vs all tasks failed.  when there are few failing tasks, it might be helpful to have an ID on hand to start the diagnosis)
