The DsMgmtTestBase abstract test shouldn't use the DataSourceSubsystemParser from the extension

The DataSourceSubsystemParser abstract test has a marshalAndReparseDsResources(String) method which uses the DataSourceSubsystemParser from the connector extension. Tests that do XML configuration parsing should be part of the unit tests not the integration tests. In this case it's a smoke test in the integration test suite.

Once done the org.wildfly:wildfly-connector should be removed as a dependency from the smoke tests.
