This patch adds a user guide that describes how to use the Neutron/Nova integration with Designate. It provides examples for Nova instance, Neutron ports and floating IPs.
Previously this information was split across Nova, Neutron, and Designate documentation.
This patch also adds a "references" section to the documentation and adds a glossary document to help explain some of our terms.
