Title: JCLOUDS-43. add scoped transaction support to ultradns-ws

Adds support to batch write operations into the same server-side transaction.

Here's the expected usage.

```
String txId = ultraDNSApi.getTransactionApi().start();
try {
// perform operations
ultraDNSApi.getTransactionApi().commit(txId);
} catch (Throwable e) {
ultraDNSApi.getTransactionApi().rollback(txId);
}
```
