Block subtractive schema changes
Drop and alter are the two main db migration operations which usually breaks the schema upgrades. To ensure smooth schema upgrades its beneficial to block subtractive operations in schema migration.
So, we need a mechanical filter to restrict subtractive schema changes by writing a simple unit test which would fail if it detects drop or alter db schema changes in the newly added migration scripts. Also, a provision will be made to take any exceptions which would allow certain subtractive schema migration changes after careful deliberation.
Cinder [1] and Nova [2] are already supporting blocking of subtractive schema operations. Would like to add similar support here.
