Adopt oslo.versionedobjects for database interactions

Registered by Ihar Hrachyshka on 2016-04-12

This blueprint will give neutron a proper object facade to hide interactions with database behind. With that, we will have a cleaner code base as well as potential to implement support for no-downtime upgrades for controllers.
