Support recovery of XA transactions

* Add method `restore_prepared_transaction` to `client_state` class
  which restores a transaction state from storage given its xid.
* Add method `commit_or_rollback_by_xid` to terminate prepared XA
  transactions by xid.
* Make sure that transactions in prepared state are not rolled back
  when their master fails/partitions away.
