Workaround for MicroProfile Config TCK "ShouldThrowException" failure

Some MicroProfile Config TCK tests expects deployment failure by annotating the @Deployment with @ShouldThrowException(DeploymentException.class).

Due to https://issues.redhat.com/browse/WFARQ-59, the deployment exception is not properly handled on the Arquillian client side and the test fails because, the thrown exception is not of the proper type.

This can be worked around by adding a DeploymentExceptionTransformer that will transform the exception into the proper type.
