updated sidecar so the health and info urls go to sidecar, but homepage and non-secure-port go to local app

This allows mappings to be at the root and not have to be prefixed.  It also allows mappings to fall through to other handler mappings.  Patterns are now Ant-style via AntPathMatcher.

The problem manifests itself as errors in the Eureka server
log (gh-47), but originates in the client because it is sending
requests to /eureka/apps/{NAME}/{ID} with the wrong ID. The
InstanceInfo has an ID that is derived (for preference) from
the EurekaInstanceConfig.dataCenterInfo, so that's the best
way to fix it.
