> we currently have {{ThriftHiveMetastore.get_open_txns()}} which maps to {{TxnHandler.getOpenTxns()}}.
 The usual usage is {{TxnUtils.createValidReadTxnList(GetOpenTxnsResponse txns, long currentTxn)}}
where the complete list transactions is obtained from Metastore and then anything above currentTxn
is thrown away.  
> Would be useful to add {{ThriftHiveMetastore.get_open_txns(long txnid)}} and {{TxnHandler.getOpenTxns(long)}}
to not retrieve things that will be thrown away.  Especially when there are a lot of running
transactions.
