fixes gh-847

This move should be transparant to users of spring-cloud-starter-eureka.

fixes gh-579

Allows for more fine-grained configuration of what to ignore.

This reverts commit 721fdc59.

If the management.port is explicitly set to something other than the
server.port, we can use it to set the status page and health URL
default values. (They can still be overridden by config properties.)

If management.port=0 there's not much we can do because we don't know
the port number yet when the instance config is created.

Fixes gh-425

Some projects were failing on `./mvnw install` due to a non-existent
local path. This makes all poms use the same approach.

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

This reverts commit 06d4d1e1.

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

fixes gh-251

fixes gh-225

update sidecare enabled property, make eureka portion of config conditional on eureka on classpath so other DiscoveryClient impls can use it.
