Corrected docs for the 'context-path' property reference.

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.

* zuul-ignored-patterns:
  If more fine-grained ignoring is needed, you can specify specific patterns to ignore. These patterns are being evaluated at the end of the route location process, which means prefixes should be included in the pattern to warrant a match. Ignored patterns span all services and supersede any other route specification.

 zuul:
  ignoredPatterns: */admin/**
  routes:
    users: /myusers/**

This means that all calls such as "/myusers/101" will be forwarded to "/101" on the "users" service. But calls including "/admin/" will not resolve.

Corrected typo in spelling of registration.

fixes gh-415

* pull434:
  Build query string from context instead of original request

Recreate query string from either getCurrentContext().getRequestQueryParams()
or original request as fallback. This allows to override query string
params in pre filters.
