From "Layout Tests on Swarming Update (and swarming Perf tests)":
"
In order to make those last two things work, what we want to do is modify the "collect" part of the swarming recipe_module
so that we can configure swarming.py to collect the results and then, optionally, we can run a user (src-side)-specified script
to postprocess the data. The script can do whatever it likes, including uploading files, but is responsible for putting
the test results into the right format expected by the recipe module. In addition, we should be able to pass back some sort
of structured data from the optional script to the step results to indicate additional links and text that we should add to the step
result.
