f6b150a34d ci: Add integration test for VM migration
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.

34412c9b41 vmm: Add id option to VFIO hotplug
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.
