Added 'version' column to ADM entities

- A patch will assign initial version values to the entities
 - Deprecated TransactionUtil in favour of the RetryingTransactionHelper
 - Renamed RetryingTransactionHelper.Callback to RetryingTransactionHelper.RetryingTransactionCallback
   The name Callback clashes with many other classes in the classpath
 - Moved loads of components to be included in the retry behaviour
Duplicate name checks
 - This is done using a query, but the entity update is not written to the database early
 - Concurrent adds of the same-named child node will only fail at the end of the transaction
 - TODO: Detect the duplicate violation during transaction retrying
Workaround for ADMLuceneTest
 - Disable session size resource management during tests
