* GH-2727: Ensure JDBC queries are logged
Fixes: https://github.com/spring-projects/spring-integration/issues/2727
The `JdbcTemplate` logs a message for the sql to execute when it is
supplied by the `QueryProvider`.
* Refactor `JdbcPollingChannelAdapter` to use new introduced internal
`PreparedStatementCreatorWithMaxRows` with the `QueryProvider`
* Refactor `JdbcMessageHandler` to instantiate a `generatedKeysStatementCreator`
based on the `PreparedStatementCreatorFactory`
* Verify in the `JdbcOutboundGatewayParserTests` that both fixes logs
sql queries properly
* * Implement all the delegate interfaces for the `PreparedStatementCreatorWithMaxRows`
