BUG REPORT

1. Please describe the issue you observed:

• What did you do (The steps to reproduce)?

When I run a cpp consumer, I found that there's no clientID information in subscription in console, but the consumer can normally consume. As follows:

Can normally consume:

Subscription detail display unusual:

Didn't show subsciption's consume type and consume mode:

• What did you expect to see?

The reason for subscription detail display unusual is the json format of ConsumeRunningInfo is incompatible with RocketMQ Java main project.

The reason for client didn't show consume type and consume mode is that c client send enum element as 0/1/2，which can't be parsed by RocketMQ Java main project.

• What did you see instead?

1. Please tell us about your environment:
