Update virtio-loopback module and adapter - priority feature

Updates [v2]
Separate the license files for virtio-loopback module
and adapter projects.

Updates [v1]
Add priority support for virtio devices handled by
virtio-loopback architecture. The new feature enables
virtio-loopback to prioritize requests (notification
and interrupts) coming from different virtio devices
based on a Round Robin scheduling algorithm and groups.
