[PATCH v3 10/11] Acceptance Tests: introduce CPU hotplug test |

Even though there are qtest based tests for hotplugging CPUs (from
which this test took some inspiration from), this one adds checks
from a Linux guest point of view.
It should also serve as an example for tests that follow a similar
pattern and need to interact with QEMU (via qmp) and with the Linux
guest via SSH.
