By setting them early, it doesn't overwrite the Transfer-Encoding:chunked header automatically set by the Reactor Netty HttpClient.
This caused bad requests to be sent downstream.

# Conflicts:

Handle 404 exceptions. Add more tests and javadocs.

* In case the failureType coming from Hystrix is SHOSRTCIRCUIT, then
ServiceUnavailableException will be thrown. That exception provides HTTP
503 to the original service consumer.
Moreover, HystrixGatewayFilterFactoryTests have been enriched so that
the aforementioned case is tested and verified.
* The hystrixFilterServiceUnavailable test of
HystrixGatewayFilterFactoryTests no longer force-closes the circuit in
order not to impact any subsequent tests (see also the comment:
https://github.com/spring-cloud/spring-cloud-gateway/pull/1230#pullrequestreview-272440126)
Adds ConversionService and deprecates ConfigurationUtils.
