Spring Cloud Openfeign Spring Cloud Circuit Breaker

Support for https://spring.io/projects/spring-cloud-circuitbreaker

Since the introduction of Spring Cloud Circuit Breaker, it would be nice if feign could base itself on it instead of only allowing hystrix.

Today, it's not possible to make use of Spring Cloud Feign fallbacks without using hystrix

Also, removing hard dependencies on Ribbon/Hystrix would remove a lot of indirect dependencies as these two libraries/the Netflix ecosystem brings a lot of stuff
