* Disable DB init for JDBC Source and Sink
The `IntegrationAutoConfiguration` provides mechanism
to initialize DB with some out-of-the-box scripts.
The default behavior is `EMBEDDED` even if we don't use
any components for those DB objects, e.g. no `JdbcMessageStore` bean.
* Add `spring.integration.jdbc.initialize-schema=NEVER` to the
`jdbc-consumer` and `jdbc-supplier` to not attempt to initialize DB
* Fix Checkstyle violations in other modules
