lack of namespace when update consumer offset by persist api in DefaultPullConsumer.

[ShannonDing]

BUG REPORT

1. Please describe the issue you observed

• update Consume Offset after pull message from remote queue. the messagequeue is warped by namespace

    @Override
    public void updateConsumeOffset(MessageQueue mq, long offset) throws MQClientException {
        this.defaultMQPullConsumerImpl.updateConsumeOffset(queueWithNamespace(mq), offset);
    }

• get offset store

@Deprecated
    public OffsetStore getOffsetStore() {
        return offsetStore;
    }

• persist offset table manually

@Override
    public void persist(MessageQueue mq) {
        AtomicLong offset = this.offsetTable.get(mq);
        if (offset != null) {
            try {
                this.updateConsumeOffsetToBroker(mq, offset.get());
                log.info("[persist] Group: {} ClientId: {} updateConsumeOffsetToBroker {} {}",
                    this.groupName,
                    this.mQClientFactory.getClientId(),
                    mq,
                    offset.get());
            } catch (Exception e) {
                log.error("updateConsumeOffsetToBroker exception, " + mq.toString(), e);
            }
        }
    }

the offset will not update to broker as the offset can not be found in the offsettable.
