9e7e64d2a3 tests: Port various integration tests to new methodology
This patch ported many tests to the new methodology, where the guest log
will be printed only when the test is failing.

Things to finish in follow-up PRs:

1. Special tests not ported yet include: test_reboot,
test_bzimage_reboot, test_serial_null(), test_serial_tty(),
test_serial_file(), test_virtio_console(), test_console_file(),
and test_simple_launch.

2. Few direct calls to 'Command::new(clh_command("cloud-hypervisor"))',
which is still printing the guest console

42f963d6f2 main, vmm: Add new --numa parameter
Through this new parameter, we give users the opportunity to specify a
set of CPUs attached to a NUMA node that has been previously created
from the --memory-zone parameter.

This parameter will be extended in the future to describe the distance
between multiple nodes.

For instance, if a user wants to attach CPUs 0, 1, 2 and 6 to a NUMA
node, here are two different ways of doing so:
Either
	./cloud-hypervisor ... --numa id=0,cpus=0-2:6
Or
	./cloud-hypervisor ... --numa id=0,cpus=0:1:2:6
