> Currently in RaftServerImpl#writeAsyncImpl() the client request is added to
> the pending requests asynchronously.
> In between if there is any failure/exception in appendTransactions() then we
> are not cancelling the transaction. The failure is returned to the
> client/retry-cache, but the statemachine is not notified.
> This can cause partial state in the statemachine.
> We should handle this such that in case of exceptions the statemachine is
> notified via cancelTransaction().
