ideally we should just get config via the standard kafka map<string,string>; client.id would be one of the many kafka config options conveyed with that method

You mean the "replicate whatever the default Java client in some version X does"? 😉

Yeah; don't know how common that is across other client libraries. But the core idea is that every time we support a new parameter in rskafka we shouldn't also have to add some code in the caller (e.g. iox) just to make use of the parameter when ultimately it's likely to come from a config env string.
