Ignore 'Connection: close' header from stream response

This commit resolves an issue where some versions of Cloud Foundry are
setting the 'Connection: close' HTTP header in the Hystrix stream
response, which causes the dashboard to not display the stream data.

Docs: Example of static, loadbalanced Zuul configuration

Exlude mockito all

However turbine and zuul are depending on mockito-all in compile-scope. Not only I want to get rid of these (usually) test-dependencies, but also mockito-all contains some hamcrest-classes (in older versions) getting in conflict with the classes from spring-test

fixes gh-276

It took me quite a bit, to figure out how to configure Zuul to use a loadbalanced route without Eureka. I hope this short explicit example will clarify it for other people.

If the app has a context path then the route locator does not match
the whole requestURI (as provided by the raw servlet API), but Spring
has a utility for stripping it off, so we can just use that.

Fixes gh-270

If there is a default route (/**) then the ZuulHandlerMapping will
mask the /error path in a normal Spring Boot application. This change
makes it a special case so that ZuulHandlerMapping will never map
the /error route (the one specified by the ErrorController).

This was kind of ugly, and caused a static usage of the eureka
DiscoveryCLient to become necessary again, just so the @Bean that is
provided for the user stays accurate (it has to be the one in the main
application context, even if the parent boot strap has different
instance metadata).

I tested with a vanilla Eureka server and config server, and used the
client in tests/eureka-first.

Added a LocalApplicationHealthCheckHandler that checks the local app and sends the appropriate status to eureka.

removes ugly dagger dependency

updated documentation of HystrixHealthIndicator

documentation was not conform to specified behavior as in #24

Simple solution is to check for instanceof before casting.

Fixes gh-265

This change adds more data to the stream with {"type":"Ping"}
so (I believe) the existing dashboard client will discard it,
but stay alive.
