Based on the notes from the Newton summit etherpad:
https://etherpad.openstack.org/p/newton-nova-summit-priorities
I've decided to omit non-priority stretch goals like
volume multi-attach since that is still a moving target.
The priority of that work can be re-assessed if we complete
some of the items in this list early enough to take on more
work before feature freeze, and it doesn't impact our other
priorities.
