Merge these, removing an unnecessary layer of abstraction, and place them in the new 'nova.db.main' directory. The resulting change is huge, but it's mainly the result of 's/sqlalchemy import api/main import api/' and 's/nova.db.api/nova.db.main.api/' with some necessary cleanup. We also need to rework how we do the blocking of API calls since we no longer have a 'DBAPI' object that we can monkey patch as we were doing before. This is now done via a global variable that is set by the 'main' function of 'nova.cmd.compute'. The main impact of this change is that it's no longer possible to set '[database] use_db_reconnect' and have all APIs automatically wrapped in a DB retry. Seeing as this behavior is experimental, isn't applied to any of the API DB methods (which don't use oslo.db's 'DBAPI' helper), and is used explicitly in what would appear to be the critical cases (via the explicit 'oslo_db.api.wrap_db_retry' decorator), this doesn't seem like a huge loss.
