Description

When NetworkClient.java gets a response error, it runs:

            if (response.errors().size() > 0) {
                log.warn("Error while fetching metadata with correlation id {} : {}", header.correlationId(), response.errors());
            }

Logging that at warn level and saying there is an error, is confusing to new people. They don't see it was a warn and not error level. They just see that it says "Error while...".

Maybe it should be something like "The metadata response from the cluster reported a recoverable issue..."
