* Renaming spring-hadoop-test to spring-hadoop-build-tests (this is now the place for integration type tests)
* Renaming spring-hadoop-test-core to spring-hadoop-test (this is test-support classes)
* Moving Abstract test classes to spring-hadoop-test

* Renaming spring-yarn-test to spring-yarn-build-tests (this is now the place for integration type tests)
* Renaming spring-yarn-test-core to spring-yarn-test (this is test-support classes)
* Moving some tests classes …
  - Moving Abstract test classes to spring-yarn-test
