Hi all,
     The Cyborg compute node specification has been published: 
https://review.openstack.org/#/c/566798/ . Please review it.

The main factors defined in this spec are:
* The behavior with respect to accelerators when various Compute API [1] 
operations are applied. E.g. On a reboot/pause/suspend, the assigned 
accelerators are left intact. But, on a stop or shelve, they are detached.
* The APIs for the newly proposed os-acc library. This is structured 
along the same lines as os-vif usage [2]. Changes are needed in Nova 
compute to invoke os-acc APIs on specific instance-related events.
* Interactions of Cyborg with Glance in the compute node. The plan is to 
use Glance properties. No changes are needed in Glance.
