Updates to Ribbon 2.10

Synchronizes on the version in use by Feign.

Closes #4920

Consolidates references to parent pom

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

* gh-337:
  Detect https from Ribbon Client Config

RibbonLoadBalancer and RibbonLoadBalancer use IClientConfig IsSecure
property for service ID to determine if the service is secure. Replaces
scheme of URI of request with https if the request is secure.

fixes gh-337

* pull485:
  Make `isSecure()` match `getPort()` in secure vs non-secure resolution

fixes gh-468

fixes gh-479

* early-eureka-client:
  make EurekaClient available before smart lifecycle phase 0

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.

fixes gh-349

so non-web apps don't break

fixes gh-475

* feign-inheritance:
  Updated documentation for Feign hierarchical clients

Via spring 4.2 new AsyncHandlerMethodReturnValueHandler

fixes gh-231

Also brings in patches to the hystrix dashboard.

fixes gh-465

It overwrote the port 443 registration.

fixes gh-461

* service-path:
  Specifing only the serviceId causes NPE

Fixes gh-463

* 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
