we do not allow db to  db interaction between services upstream.

the db scheme of each service is considered private. the public interface
to most services is teh rest api. if zun need to interact with blazar it should
do so via blazars rest api.

the RPC apis are also considerd internal apis that are not intended to be shareed between services

the only exception to this is the notifcations bus wich is a readonly stream of events for the consuming service
and write only for the publishing service.
