Not used by the app itself, but will show up in metadata reports
and in tooling, so useful for documentation purposes.

It's nice to have an annotation to say "I want Eureka discovery".
At the moment it is a pass thru for @EnableDiscoveryClient, but
in principle it could be used to select Eureka over another provider
even if both were on the classpath.

If the ClientFactory from netflix is used directly it bypasses
all the goodness in SpringClientFactory, so clients created
in Feign before this change were getting the default native
configuration instead of that provided by
RibbonClientConfiguration.

There are no remaining references to the raw ClientFactory in
Spring Cloud, so we probably have seen the last of this.

With just a bit more hackery on the Zuul request wrapper we can mask
off the input stream and content lengths, and fix them so they contain
the expected content. Doesn't work (yet) for multipart content.

Overrides Spring Boot's FreeMarkerAutoConfiguration to prefer using a
SpringTemplateLoader instead of the file system. This corrects an issue
where Spring Boot may use an empty 'templates' file resource to resolve
templates instead of the packaged Hystrix classpath templates.

When creating a new project with Spring initializer, an empty
'templates' resource directory is automatically added to the new
project, causing a scenario where this issue may occur.

The Zuul filter registry has to be cleareed (including a cache in
a private field in FilterLoader, yuck).

With this change users can elect not to install the proxy features
but still have a Zuul server with @Beans of type ZuulFilter added
automatically.

If user adds auth.route.<service>.scheme: passthru then instead
of adding the bearer token the filter will not do anything
(and the normal authorization header will be passed through
to the backend)
