Updated MARIADB schema to use sequences instead of tables for Boot 3 batch tables

[This Comment Applies to all concrete impls]

The pattern I am seeing is that a concrete subclass provides a testcontainer and then calls a base method via @BeforeEach that initializes the DB to clean slate before running each test.

The current impl requires each concrete test to do these things:

this.dataSource = createDataSourceForContainer(dbContainer);
this.jdbcTemplate = new JdbcTemplate(this.dataSource);
createDataFlowSchema(dbContainer, schemaName);

I propose that we pull up the DS and JDBCT to the AbstractDaoTests and then provide a base method called prepareForTest that can be called by the concrete tests. Something like this:

protected void prepareForTest(JdbcDatabaseContainer dbContainer, String schemaName) {
	this.dataSource = createDataSourceForContainer(dbContainer);
	this.jdbcTemplate = new JdbcTemplate(this.dataSource);
	createDataFlowSchema(dbContainer, schemaName);
}

Otherwise, all the ADT is really providing is 2 util methods that everyone has to call.

Wdyt?
