XD-721 Test Job Module addition after XD Start

This is an acceptance test that will copy batch simple job (from the spring-xd-samples project) to the targeted admin server and its associated containers.  Then create, deploy, launch and check to see if the job launched.  
It will look for the myjob.xml and springxd-batch-simple-1.0.0.BUILD-SNAPSHOT.jar in the spring-xd-integration-test directory, if it is not there the test will be ignored.

The CI Acceptance Test has been updated with a new stage that builds the spring-xd-batch-simple project and has the myjob.xml and springxd-batch-simple-1.0.0.BUILD-SNAPSHOT.jar marked as artifacts .  These artifacts have been added to the "Run Integration tests Rabbit" & "Run Integration tests Redis" jobs and will be installed in the spring-xd-integration-test directory.
