Implements forwarding of eureka CacheRefreshedEvent as HeartbeatEvent,
rather thank serialization hack. Uses new Eureka DI functionality
(mostly there, some issues). Updates EurekaJacksonCodec to be
"DataCenterAware". Reference EurekaClient interface rather than
DiscoveryClient class.
fixes gh-349
With the following configuration at `bootstrap.yaml`
```yaml
spring:
application.name: spring-cloud-hystrix-dashboard
profiles.active: prod
cloud:
config:
discovery:
enabled: true
serviceId: spring-cloud-server-config-with-eureka
server.port: 9003
turbine:
appConfig: some-service
clusterNameExpression: 'default'
```
I wasn't able to see why Turbine can't find the instance. The reason was related to SPEL:
```
org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 0): Property or field 'default' cannot be found on object of type 'com.netflix.appinfo.InstanceInfo' - maybe not public?
```
Anyways there was nothing there in the logs so maybe it should not be silenced like right now?
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
