aeeae661fc vmm: Support vhost-user-block via "--disks"
Add a socket and vhost_user parameter to this option so that the same
configuration option can be used for both virtio-block and
vhost-user-block.  For now it is necessary to specify both vhost_user
and socket parameters as auto activation is not yet implemented. The wce
parameter for supporting "Write Cache Enabling" is also added to the
disk configuration.

The original command line parameter is still supported for now and will
be removed in a future release.

f5b53ae4be vm-virtio: Implement multiqueue/multithread support for virtio-blk
This commit improves the existing virtio-blk implementation, allowing
for better I/O performance. The cost for the end user is to accept
allocating more vCPUs to the virtual machine, so that multiple I/O
threads can run in parallel.

One thing to notice, the amount of vCPUs must be egal or superior to the
amount of queues dedicated to the virtio-blk device.

08e47ebd4b vmm: Add num_queues and queue_size parameters to virtio-blk
The number of queues and the size of each queue were not configurable.
In anticipation for adding multiqueue support, this commit introduces
some new parameters to let the user decide about the number of queues
and the queue size.

Note that the default values for each of these parameters are identical
to the default values used for vhost-user-blk, that is 1 for the number
of queues and 128 for the queue size.

0fa1e2c241 vmm: Handle mapping from devices regions through vm-memory
Devices like virtio-pmem and virtio-fs require some dedicated memory
region to be mapped. The memory mapping from the DeviceManager is being
replaced by the usage of MmapRegion from the vm-memory crate.

The unmap will happen automatically when the MmapRegion will be dropped,
which should happen when the DeviceManager gets dropped.

694da82691 ci: Make the integration tests fail if images are not valid
When the CI runs in a brand new VM, there's no problem with the validity
of the images as they just got downloaded from the Azure bucket.

In case of a user who runs the CI locally, while doing some debug, he
might provision the images with cloudinit at some point, and later try
to run the CI based on these same images. What happens is that the CI
might randomly fail because the provisioning will not happen again as
it already happened.

This patch ensures the CI to fail early and show an error message to
notify the user about the validity of the images, based on their
sha1sum.

Fixes #112

swapped. The data buffer was provided with the actual offset, while the
offset was provided with the actual all 1's dword. We were effectively
trying to write the real offset at the offset 0xffffffff, which was
