The newly added integration test "test_snapshot_restore" is very

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

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.

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.
