Support booting overcloud nodes from Cinder volumes

Registered by Dmitry Tantsur on 2016-12-01

Ironic is introduces boot-from-volume feature in the Ocata cycle (hopefully):
http://specs.openstack.org/openstack/ironic-specs/specs/approved/boot-from-volume-reference-drivers.html
http://specs.openstack.org/openstack/ironic-specs/specs/approved/volume-connection-information.html
When it lands, we'll be able to use Cinder volumes for overcloud nodes (incl. as root devices).

The following changes should be applied to TripleO specifically:
* Deploying and configuring Cinder on undercloud
* Ability to create volumes from the overcloud-full image and assign them to profiles (?)
* It seems like Nova blueprint https://blueprints.launchpad.net/nova/+spec/ironic-boot-from-volume won't land soon, so we'll have to do some integration bits in Mistral.
