Instead of blindly waiting for 20-40s for the guest VM to boot, this
patch waits the notification from the guest VM explicitly by using a
simple TcpListener on the host and a custom systemd service in the
guest.
This patch also ported few tests to use this new machanism, while more
tests are to be ported.

This is a new integration test running Windows as a guest with Cloud
Hypervisor. Once the VM is booted, the test connects to the guest
through SSH and shutdown the VM. If this succeeds, this means the VM
was properly booted to userspace and that the network was functional.
Important to note that because this test generates lots of logs, it
requires a large pipe size for both stdout and stderr.

Since all unit and integration tests are run inside containers because
they are called from dev_cli.sh, they always run as root. That's why
both unit and integration scripts can be simplified as they don't need
to apply specific capabilities and run cargo tests in a dedicated 'kvm'
group.

As discussed in #1707, the `vcpu` thread can be stalled when using
`--serial tty`. To workaround that issue, this patch enforces to resize
the pipe size to 256K when we capture the stdout/stderr of the
cloud-hypervisor child process in the integration tests. Note that the
pipe size (256K) is chosen based on the output size of our integration
tests at this point, which may need to be increased in the future.

Now that virtio-mem supports reboot, we extend the existing integration
tests to validate the amount of RAM after reboot is the same as before
the reboot, but also that we can still resize down the VM or the memory
zone after the reboot.

The goal of this commit is to rename the existing NUMA option 'id' with
'guest_numa_id'. This is done without any modification to the way this
option behaves.
The reason for the rename is caused by the observation that all other
parameters with an option called 'id' expect a string to be provided.
Because in this particular case we expect a u32 representing a proximity
domain from the ACPI specification, it's better to name it with a more
explicit name.

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
