spring.kafka.bootstrap-servers overrides brokers configuration of every binder.

See original GitHub issue

Hi, I have to configure two separate kafka brokers (as on example below) and this is working just fine.

spring:
  cloud:
    stream:
      binders:
        kafka1:
          type: kafka
          environment:
            spring:
              cloud:
                stream:
                  kafka:
                    binder:
                      brokers: dev1-stage.dub:9092
        kafka2:
          type: kafka
          environment:
            spring:
              cloud:
                stream:
                  kafka:
                    binder:
                      brokers: dev2-stage.dub:9092
      bindings:
        firstOut:
          destination: first_topic
          binder: kafka1
        secondOut:
          destination: second_topic
          binder: kafka2

But also I need to configure zipkin+sleuth in application - and only way I can do for this for kafka sender type is via adding.

spring:
  kafka:
    bootstrap-servers: dev1-stage.dub:9092

As soon, as spring.kafka.bootstrap-servers added, it started to override kafka2.environment.spring.cloud.stream.kafka.binder.brokers - so application just trying to write to kafka on dev1-stage.dub, instead of dev2-stage.dub.

How can I prevent this overriding?
