Review comment:
Thank you for the review @azagrebin and @aljoscha.
I looked at the kafka document again, for `kafka consumer`, group.id is a
required property.
- for old consumer, the default value set "group.id value".
- for new consumer, the default value set "".
so, i agree with @aljoscha, clear and concise.
```
this.clientId = config.getProperty("client.id",
"flink-kafka-consumer-legacy-" + broker.id());
```
If ok, I'll resubmit it again, thanks.
