[C extension]some c interface enhancement and bugfix during user using python sdk

**BUG REPORT**

1. Please describe the issue you observed:
When we extend the Python sdk with the c interface of the c++ sdk, we find the following question:

- [x] **task 1** [#398] When we open message trace，client log shows follow error:
`(error):processSendResponse error remark:topic[rmq_sys_TRACE_DATA_DefaultRegion] not exist, apply first please!
See http://rocketmq.apache.org/docs/faq/ for further details., error code:17[processSendResponse:552]`
- [x] **task 2** [#400] Setting the log path does not take effect，set log path interface not implemented
```
int SetProducerLogPath(CProducer* producer, const char* logPath) {
if (producer == NULL) {
return NULL_POINTER;
}
return OK;
}
```
- [x] **task 3** [#402] The json format of ConsumeRunningInfo is different from the format required by the broker side, resulting in an error in the display of subscription group details

- [ ] **task 4** The obtained local IP in clientID is 127.0.1.1

- [x] **task 5** [#404] By using Python sdk，the language displayed by the console was still "CPP"，should add c interface to change language type.

- [ ] **task 6** The configuration of the single log size and the maximum number of saved logs does not take effect.
