Review comment:
Originally the idea was that we didn't want the SDK to have to perform
these calculations and it is why each operator was going to report
work_completed/work_remaining if it had them but it seems like accurate
splitting by fraction needs to take it into account.
Using the graph to compute the progress shouldn't be any more/less difficult
then the work that is being put into the SDK.
Is there still value in reporting the work_completed/work_remaining metrics
then?
