This new wrapping structure allows for a better factorization of the
Windows specific code. This makes each test simpler and easier to read.

By using a Box around the DiskConfig trait, it becomes Sized. For that
reason, we can pass the DiskConfig to the Guest so that it can own it.
This allows for further simplification as the Guest does not need to be
bound to a specific lifetime, which makes things easier.

Relying on latest changes from vhost_user_backend crate, this patch
enables the client mode support for vhost-user-net backend.
In this mode, the backend behaves as a client instead of the default
mode where it behaves as the server.

The point being to identify clearly that we're running the backend as a

backend as a client.

Adding the support for an OVS vhost-user backend to connect as the
vhost-user client. This means we introduce with this patch a new
option to our `--net` parameter. This option is called 'server' in order
to ask the VMM to run as the server for the vhost-user socket.

In some situations (booting with OVMF) fewer queues will be enabled
therefore we should iterate over the number of enabled queues (as passed
into VirtioDevice::activate()) rather than the number of create tap
devices.

Create a temporary copy of the config, add the new device and validate
that. This needs to be done separately to adding it to the config to
avoid race conditions that might be result in config changes being
overwritten.

Relying on guest Ubuntu image 21.04, including a 5.11 kernel, this patch
adds some additional tests to the VFIO baremetal integration tests. It
adds a test for ACPI memory hotplug, another one for virtio-mem memory
hotplug, and finally a test for hotplugging the NVIDIA card.
The existing test already taking care of the reboot has been renamed.
The script running "cargo test" has been modified to run only one thread
at a time, so that each test run sequentially. This is mandatory since
the card can't be shared across multiple VMs.

In order to support most recent Ubuntu distributions, we must update
the way of detecting a reboot through the journal since there is no
more "-- Reboot --" logs.
Using the `--list-boots` option is the preferred way for getting the
boot count information from journalctl command. We simply need to add 1
to the count in order to get the reboot count.

Cleanup the control queue handling in preparation for supporting
alternative commands.
Note that this change does not make the MQ handling spec compliant.
According to the specification MQ should only be enabled once the number
of queue pairs the guest would like to use has been specified. The only
improvement towards the specication in this change is correct error
handling if the guest specifies an inappropriate number of queues (out
of range.)
