rpc_available_version and object_available_version columns were part of
previous design of our RPC API compatibility layer. We've decided to go
in a little different direction so these two are currently unused.
With our live-schema-upgrades guidelines (related to rolling upgrades
support) it's a lot easier to readd something to the DB than to drop it.
Let's take the chance to actually drop these unused DB columns in early
Newton. To do that we need to remove them from the SQLAlchemy model in
Mitaka and this commit does so.
