Implement XA recovery in TransactionXaAdapter

We currently don't support any sort of recovery from transaction failures.
E.g.
tm.start();
database.delete(account);
ispnCache.put(account);
tm.commit():
At tm commit:
-prepare is successful on both enlisted resources.

• database.commit - fails
  What shall we do with the locks/state from ispnCache.
  Possible solutions:
• configure to automatically commit/rollback after a timeout
• keep locks on resources and allow manual intervention through JMX
• others?
