distributed tests of a patch

Not only would this would help DPDK, but I also think this has broad appeal for many other projects (such as Open vSwitch or QEMU). The mailing list-based workflow is still a great option in the era of Gerrit/GitHub pull-request workflows, but accessible automated testing integration is basically nigh on impossible. Patchwork as it stands is a great complement to a development mailing list, but the addition of this pseudo-"CI integration" could be another killer feature.

I have been working on a similar feature on and off for a few months and will accelerate development of it now (est. end of next week). In the interim, I have included some links below where you can find my WIP code and documentation. I'd love to get peoples' feedback on these changes. Hopefully this is something people want, and (just as importantly for me heh) I'm going about it the correct way.

Cheers,
Stephen
