  === Hystrix GatewayFilter Factory
  https://github.com/Netflix/Hystrix[Hystrix] is a library from Netflix that implements the https://martinfowler.com/bliki/CircuitBreaker.html[circuit breaker pattern].
  The Hystrix GatewayFilter allows you to introduce circuit breakers to your gateway routes, protecting your services from cascading failures and allowing you to provide fallback responses in the event of downstream failures.
  
  To enable Hystrix GatewayFilters in your project, add a dependency on `spring-cloud-starter-netflix-hystrix` from https://cloud.spring.io/spring-cloud-netflix/[Spring Cloud Netflix].
  
  The Hystrix GatewayFilter Factory requires a single `name` parameter, which is the name of the `HystrixCommand`.
