[infinispan-dev] Test cleanup

Hey guys, I do not know the details behind the decision to run cleanup after each test method in all subclasses of MultipleCacheManagersTest but the consequence is that the testsuite execution is indeed really slow. After each test method execution we are killing JGroups instances and then recreating at least two of them who then have to find each other, join, create a cluster before the next test method can be run again. There is no reason why we cannot run a check after each test method to ensure that cache instance are totally pristine and in the case the are not we can kill them and only then recreate cluster. Cheers
