Introducing Spock/Groovy for Data Integration Tests

Replaced CpsAdminPersistenceServiceTest with CpsAdminPersistenceServiceSpec
Replaced CpsDataPersistenceServiceTest with CpsDataPersistenceServiceSpec
Replaced CpsModulePersistenceServiceTest with CpsModulePersistenceServiceSpec
Extracted out common integration test base
Rationalised test (there was a lot of duplication already!)

Issue-ID: CPS-160
