Liquibase Command updateSql

Liquibase reads the ChangeSet file, generates database-dependent SQL, and executes them, but sometimes, before actually running DDL and DML queries, it's a good practice to actually see the queries. Liquibase provides a updateSql helper command which lets the user inspect the raw SQL.
