This PR changes default ExampleDS configuration to disable H2 DatabaseCloser thread creation which can hold reference to hibernate CL.

This same problem exists also in this quickstart
https://github.com/wildfly/quickstart/blob/master/kitchensink-html5-mobile/src/test/resources/arquillian-ds.xml also needs this change 
;DB_CLOSE_ON_EXIT=FALSE should be added to url.

with that change memory leak does not appear anymore.

This problem is related only to h2 in memory database and does not affect any other jdbc drivers I was testing.

If I run quickstart with modified datasource this memory leak does not appear anymore
