Tag a test as 'integration/system' test, meaning that the test class has the following
 characteristics:
 
 - Possibly takes hours to complete
 
 - Can be run on a mini cluster or an actual cluster
 
 - Can make changes to the given cluster (starting stopping daemons, etc)
 
 - Should not be run in parallel of other integration tests
 
 
 Integration / System tests should have a class name starting with "IntegrationTest", and should
 be annotated with @Category(IntegrationTests.class). Integration tests can be run using the
 IntegrationTestsDriver class or from mvn verify.
