Discovery service properties naming

[jmnarloch]

This is a minor issue, although the discovery service naming seems inconsistent, Eureka uses it's own root 'eureka': eureka.client.serviceUrl, while consul is under spring.cloud.consul, ie.:

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka

spring:
  cloud:
    consul:
      host: localhost
      port: 8500

spring-cloud-netflix has some naming so it can retain the same properties that eureka archaius uses. The other projects are more standardized. Not sure I want to do anything about this.
