Fix minor misspelling in docs

The Angel client has an idiosyncratic way of calculating an instance
id, and the Brixton client aligned with that already, but the
Brixton server did not. This change should make Brixton Eureka
Servers work with Angel clients.

See gh-978

The way it was being used internally means that we didn't need the
annotation anyway. It would be nice to have it back if the Spring
issue gets resolved, because then we could actually use it as
intended.

Fixes gh-1025

This reverts commit 2c502e39.

This commit adds the support for query string defined in the class'
@RequestMapping Annotation that is applied to all method of a
controller.

Fxies gh-1023, fixes gh-1024

Before this change we were seeing test failures in
spring-cloud-netflix-eureka-server (but only with Spring Boot 1.4)
caused by annotation processing explosion when
RefreshScopeAutoConfiguration is not on the classpath.

This test should run with Spring Boot 1.4.0.M2 now.

See https://github.com/spring-projects/spring-boot/issues/5870

When the users explicitly sets the sensitive headers of a rroute to
empty, it means they should be empty, not the global defaults.

Fixes gh-1012

* pull1007:
  Updating RxJava version to 1.1.5 This update on RxJava version is in regards to the PR that got merged [`here`](https://github.com/ReactiveX/RxJava/pull/3820) for making RxJavaPlugins' `reset` method to be public. We have to work this around in Spring Sleuth. Details on the implementation can be found [`here`] (https://github.com/spring-cloud/spring-cloud-sleuth/pull/243).

1.1.5

The jackson version needs to be explicit (not in parent potentially)
and there is a weirdness with @RequestMapping in Spring 4.3

* fix-IgnoredHeadersCasingNotIgnored:
  Sensitive headers set in PreDecorationFilter no longer override previously set ignored headers. Removed the case sensitiveness when the sensitive headers are set. Fixes https://github.com/spring-cloud/spring-cloud-netflix/issues/1003
  Test for default ribbon client configuration
  Tidy up more compiler warnings for generics
  Add note to clarify that zuul starter does not include discovery
