Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a VFIO device should be attached to the virtual
IOMMU or not. That's why we introduce an extra option "iommu" with the
value "on" or "off". By default, the device is not attached, which means
"iommu=off".

Because the L2 VM running in the VFIO integration test is actually
running as L3 (since the CI runs in a VM), it can take quite some
time for this VM to boot.
The way to solve this issue is to extend the sleep time before to try
communicating with the L2 VM, but also to speed up the boot time by
using virtio-console instead of serial. We suspect the use of serial,
implying PIO VM exits for each character on the serial port is quite
expensive compared to the paravirtualized console.

Now that cloud-hypervisor can expose a virtual IOMMU to its guest VM,
the integration test validating the VFIO support with virtio-net can be
updated to use cloud-hypervisor exclusively.

Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a virtio-blk device should be attached to this
virtual IOMMU or not. That's why we introduce an extra option "iommu"
with the value "on" or "off". By default, the device is not attached,
which means "iommu=off".
One side effect of this new option is that we had to introduce a new
option for the disk path, simply called "path=".

Rely on the newly generated Clear Linux image for the integration
testing of cloud-hypervisor. The image has been generated using the
Clear Linux clr-installer tooling, which means it is in compliance with
the Clear Linux licensing.
This new image contains one more bundle that was not part of the default
cloudguest image. This bundle is basic-sysadmin, and contains both nc
and socat utilities.

And rename the default user from "admin" to "cloud" as the admin user
clashes with a standard user and group name on Ubuntu.
