Now that we have multiple virtio devices supporting snapshot and restore
operations, we can add a new integration test to validate the migration
feature works as expected.
The important part is virtio-net as it is used to ssh into the VM to
verify the VM has been restored in the proper state.
This test only works for virtio-mmio for now. Further support for
testing virtio-pci will be added once the virtio-pci transport layer
will support migration.

There is some duplication between regular and hotplug virtio-fs tests
that can be factorized by adding a simple hotplug flag to choose if each
test should run with or without hotplugging the device.

One more time, we're extending the VFIO integration test to verify that
a VFIO device passed through a VM is still usable after some new memory
has been hotplugged.

the integration test creates an initramfs image based on AlpineLinux mini root filesystem
with a simple /init script that just echoes a string to the console. The string
is passed via the kernel cmdline as an environment variable.

All vhost-user-blk, vhost-user-net and virtio-fs integration tests are
extended with memory resizing. The point is to validate that we can
hotplug some memory and keep these backends to work as expected.
Just a note that because memory resizing is not supported by mmio, we
limit these extensions to all non-mmio use cases.

The same Clear Linux kernel command line was repeated again and again in
the code. That's why this commit takes care of factorizing it, which
simplifies the code but also simplify maintenance whenever we'd need to
update the block UUID.

The hypervisor-fw does not support virtio-blk through mmio transport
layer, therefore we can only run tests with mmio if these tests boot
directly to kernel.

There's no reason mmio builds cannot support vhost-user-blk, therefore

As a first step towards factorizing as many vhost-user-blk tests as
possible, this patch takes care of unifying their expected output.
It also makes a clear separation between the tests booting from
vhost-user-blk from the ones passing an extra volume.

Add a new id option to the VFIO hotplug command so that it matches the
VFIO coldplug semantic.
This is done by refactoring the existing code for VFIO hotplug, where
VmAddDeviceData structure is replaced by DeviceConfig. This structure is
the one used whenever a VFIO device is coldplugged, which is why it
makes sense to reuse it for the hotplug codepath.

A new ClearLinux image has been uploaded to the Azure storage account.
It is based off of the ClearLinux cloudguest image 31310 version, with
three extra bundles added to it.
First bundle is curl, which adds the curl binary to the image, second
bundle is iperf, adding the iperf binary to the image, and third bundle
is sysadmin-basic to include utility like netcat.
The image is 2G in size.

On tests that expect a clean shutdown there is no need to try and kill
the child after wait() has returned as the process has already exited.
Further there is no need to sleep before wait() as wait will block until
the VM and VMM shutdown is complete.

Many of the tests attempted to SSH into the VM and then run "shutdown"
but don't actually check that the VM has shutdown correctly and proceed
to kill the child process. Remove the associated SSH commands and sleeps
from those tests that are not explicitly checking the shutdown
behaviour.
