Added alembic, and created an initial database revision. For the sake of testing with real databases, tools/test-setup.sh is added so that CI can start up a mysql and/or postgresql database on which to test migrations. The OpportunisticDBMixin from oslo_db was originally used for this, but because of the way placement configures the database this proved hard to debug and get correct, so we've used something that leverages the available oslo_db tools, but with more visibility. Because these tests mix sqlite, mysql and postgresql settings in the potentially the same process we need a way to insure that global settings for databases do not leak into other tests. This is done with a reset() on the placement db fixture, called by the msyql and postgresql tests before and after they run. We also need careful management of that cleanup when these tests are skipped (because db server or database is not there). Those tests will confirm that the models match the migrations so we also need to remove model files that no longer matter. Since we no longer need to distinguish among multiple database files, we can simplify the naming of these files.
