MySql script not idempotent #20
Description
Running aws-database-migration-samples/mysql/sampledb/v1/install-rds.sql failed due to [this bug]. Fixing it was simple enough, but re-running required a number of changes since the scripts are not idempotent. Ideally, there'd be a DROP TABLE IF EXISTS table_name; before each CREATE TABLE, and DROP USER IF EXISTS before the dms_user is created.
