def successful: Boolean = finished && !failed && !killed
So if the task state shows finished and it has neither failed nor been
killed, then info.successful is true. Now, there could be multiple reasons for
a failed or killed task, and taskEnd.reason lists those. However, if task state
is SUCCESS, so is the reason and thus, info.successful will be true in case of
SUCCESS and false for all the other cases.
