[dpdk-ci] Add guest device assignment tests to CI loop

[Maxime Coquelin]

Hi Qian,

In DPDK v17.11, we have hit a regression impacting guest device
assignment with vIOMMU enabled [0][1] (e.g. using vfio without noiommu
mode).

Do you think we could add some tests around this feature in the CI lab?
It would be better to catch these regressions as early as possible.

Let me know if you need more details about the test case.

Cheers,
Maxime
