CI testing on a real Kobuki

[slivingston]

I propose to add integration with a CI testing service that runs on a real Kobuki robot. Can I get your feedback:

1. is there already something like this, or does everyone just manually try code on their own Kobuki?
2. for tests, should I just collect output from kobuki_testsuite ?
3. assuming you want this, is sending a pull request the best way to offer it?

I made a basic system for time-sharing robots, and now I am building services on top of it. You can try an interactive sandbox: https://rerobots.net/sandbox/multi_kobuki?e=rospy (also there is a screenshot on Twitter). The robot is physically in SF Bay Area, so expect some latency. However, automated tests (proposed in this issue) would run entirely locally, so latency would not be significant for CI testing.

This work could make reviewing PRs like #9 easier.

I need to free up some time to make a concerted push on this again - next step really is to prop them up with test suites and drop them on the OSRC build farm (with github hooks). We really can't advance the source code beyond this first pass with confidence unless we have that automated testing. If you can make a PR to kobuki_testsuite I'd be happy to review it (actually any other testing as well).

@stonier thanks. I will begin work on that.
