Switch to using kwargs to invoke the RunTool task.
Review Request #8903 — Created April 17, 2017 and submitted
Using a big list of arguments is kind of fragile to version mismatches that
might change the "protocol" of the
RunTooltask invocation. This change
switches over to passing things via kwargs, which can be extended in the
future without causing errors.
