By default, `LoadBalancerBuilder` built a load-balancer with a `PollingServerListUpdater`. This change introduces a `ServerListUpdater` bean which creates a `PollingServerListUpdater(IClientConfig)` so that `ribbon.ServerListRefreshInterval` is respected.
fixes gh-1304
Fix a suspected typo. @Autowired throws a `NoUniqueBeanDefinitionException` if there are multiple beans of the same type without a primary, but the documentation said multiple beans 'cause `@Autowired` to work', rather than 'not work'.
As discovered in #1643, using `@Configuration` on a custom configuration with `@FeignClient` is unnecessary and creates extra work for exclusion from a `@ComponentScan`. This updates the docs to make this explicit.
Some webserver are picky with the encoding (uWSGI for example) and the current code behavior of decoding and reencoding the query string can lead to valid requests
rejected by the backend after the modifications in Zuul. This commit adds an optional parameter to force the original encoding of the query string in SimpleHostRoutingFilter.
Fixes gh-971
