BUG-6111: implement PingPongTransactionChain cancelation
This patch implements transaction cancelation in PingPongDataBroker,
which has slightly different semantics -- if a transaction is canceled
while being in a batch, proper isolation of the batch is maintained
and after preceding batch completes, the transaction chain is aborted.
Since there is no transaction isolation within a batch, this is the
only course of action we can take.
