Issue XD-3550: Re-add Spark job acceptance test with spark standalone cluster 
The spark app test on spark standalone cluster is currently commented out: https://github.com/spring-projects/spring-xd/blob/9307f1fba347adf59c8b489ae7fe0aa9bfd9b6a6/spring-xd-integration-test/src/test/java/org/springframework/xd/integration/test/SparkAppTests.java#L74 We need to add it back once the cluster is setup on acceptance test environment.
