Robot Tests in CI

[Andrew Geissler]

I've enabled running our robot CI tests against all of the
openbmc/openbmc gerrit commits.  This is against the basic ARM based
QEMU model.

Reviews/Comments (or +1's) appreciated on the scripts to do this:

https://gerrit.openbmc-project.xyz/#/c/166/  (main script)
https://gerrit.openbmc-project.xyz/#/c/176/  (minor change to support
QEMU in docker)

The jenkins job can be found here:

The test team is working on optimizing the test suite to ensure as
much coverage in as minimum amount of time.

Also, I've tweaked the build-setup.sh script to support ppc64le,
comments (or +1's) appreciated here as well:

Next on the list is a real-hardware based CI job.
