The "MAX" constants in the db api are useful to import without needing to import the rest of the api, so they are moved to a constants.py file in the same package. api.py then imports the symbols from that file for backwards compatibility. The handler and schema for placement inventories (which use the MAX constants) are updated to point to the constants file directly as they do not need the db api.
