In the context of trying to configure Rabbit, the docs mention that the Rabbit config properties be added under `rabbit`:
```
...
binders:
rabbit1:
type: rabbit
environment:
spring:
rabbit:
host: <host1>
...
```
however, the properties should be configured under `rabbitmq` as reference in the [Spring Boot Appendix A](https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html)
