Users need to know how to configure and use the Eureka
metadata because it isn't immediately obvious and does
require some decisions to be made.

and also allow explicitly configured services to be unignored. I.e.

zuul:
  ignoredServices: *
  routes:
    foo: /foo/**

Will expose only the foo service.

The Eureka instance has to provide status page and health check
URLs. We only provide a sensible default if the app is a vanilla
Actuator. This change shows users explicitly how to customize those
settings.

The ProxyRouteLocator now has a retryable property (default
null which means Ribbon will choose the default - usually false).

Fixes gh-115, fixes gh-124

Adds a metadataMap for the Server.zone so that user can
provide the data through external configuration if needed.

Replaces the boolean flag (loadbalance) for switching between service
resolution (by name) or straight URL bashing.

added preferIpAddress section to eureka and updated ribbon docs to show what beans are created by default and how to override them.

This change adds an ApplicationListener that sets some high priority
properties in the Environment to allow server.port and management.port
to keep their usual meaning, but have server.port apply only to turbine.
Actuator endpoints can be enabled with management.port (different to
server.port otherwise there will be a conflict between Netty and Tomcat).

With this change users can elect not to install the proxy features
but still have a Zuul server with @Beans of type ZuulFilter added
automatically.

The default behaviour is now to strip the prefixes (global and
route-specific) by default. E.g.

zuul:
  prefix: /api
  routes:
    customers: /customers/**

Will forward /api/customers/101 to /101 on the customers service

See gh-43

We now support prefix stripping per service, e.g.

zuul:
  routes:
    customers:
      path: /customers/**
      stripPrefix: true

Will route /customers/101 -> /101 (on the customers service)

See gh-77

User can now specify zuul.routes.*.{path,url,serviceId} (with
"url" and "serviceId" mutually exclusive (and "location" is a
synonym) separately, or can use a one-one short form, like the
old style.

See gh-77

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.
