Move some Nova-Cinder interactions to events

Registered by Nikola ─Éipanov on 2014-04-11

Nova allows other services to notify it about events it may be waiting using it's REST API (introduced in https://blueprints.launchpad.net/nova/+spec/admin-event-callback-api), and Neutron already uses it for certain interactions. This is a model that will work well with Cinder too, especially since a lot of places where nova needs to interact with cinder - we are simply doing dumb polling. There is work needed on the Cinder side as well, to make it send events to nova.
