In order to avoid regression regarding OVS-DPDK support, a new
integration test is added. This test consists of running two VMs, both
attached to a distinct OVS port, where both ports are connected to an
OVS bridge. Once the VM are running, the test validates the connection
between the two VMs works correctly.

Adding a new function ssh_command_ok() as a wrapper around the existing
ssh_command() function. The goal being to identify if the command
returned without any error.
This new function allow for a bit of factorization through the codebase.

The Dockerfile is extended with some new instructions to install the
OVS-DPDK packages. This will be useful for writing new integration tests
and make sure OVS-DPDK is working properly.
This also updates the Rust toolchain from 1.51.0 to 1.52.1.

We recently realized the control queue is not meant to be handled by the
backend, that's why we move it out of vhost-user-net implementation.
Revert "vhost_user_net: Handle control queue"
This reverts commit af88ff1c49.

We thought we could move the control queue to the backend as it was
making some good sense. Unfortunately, doing so was a wrong design
decision as it broke the compatibility with OVS-DPDK backend.
This is why this commit moves the control queue back to the VMM side,
meaning an additional thread is being run for handling the communication
with the guest.

A lot of the VIRTIO reserved features should be supported or not by the
vhost-user backend. That means on the VMM side, these features should be
available, so that they don't get lost during the negotiation.

On FDT, VMM can allocate IRQ from 0 for devices.
But on ACPI, the lowest range below 32 has to be avoided.

This commit enables the PSCI (Power State Coordination Interface)
for the AArch64 platform, which allows the VMM to manage the power
status of the guest. Also, multiple vCPUs can be brought up using
PSCI.

This commit implements the IO Remapping Table (IORT) for AArch64.
The IORT is one of the required ACPI table for AArch64, since
it describes the GICv3ITS node.

This commit implements an AArch64-required ACPI table: Serial

This commit implements an AArch64-specific ACPI table: Generic
Timer Description Table (GTDT). The GTDT provides OSPM with
information about a system’s Generic Timers configuration.
The Generic Timer (GT) is a standard timer interface implemented
on ARM processor-based systems.

Simplified definition block of CPU's on AArch64. It is not complete yet.
Guest boots. But more is to do in future:
- Fix the error in ACPI definition blocks (seen in boot messages)
- Implement CPU hot-plug controller

The VIRTIO features should not be set before they are acked from the
guest. This code was only present to overcome a vhost crate limitation
that was expecting the VIRTIO features to be set before we could fetch
and set the protocol features.
The vhost crate has been recently fixed by removing the limitation,
therefore there's no need for this workaround in the Cloud Hypervisor
codebase anymore.

Everything that was shared in the net_util.rs file has been now moved to
the net_util crate. The only remaining bit was only used by the
virtio-net implementation, that is why this commit moves this code to
virtio-net, and since there's nothing left in net_util.rs, it can be
removed.

Make sure the virtio features are set upon device activation. At the
time the device is activated, we know the guest acknowledged the
features, which mean it's safe to set them back to the backend.
