archaius-core not used outside test

[mikrethor]

When investigating why my project was getting commons-lang 2.6 I found out it was coming because archaius-core.
Looking forward, it seems it's only use for test purpose.

Change pom.xml in feign-hystrix from :

    <dependency>
      <groupId>com.netflix.archaius</groupId>
      <artifactId>archaius-core</artifactId>
    </dependency>

to

    <dependency>
      <groupId>com.netflix.archaius</groupId>
      <artifactId>archaius-core</artifactId>
      <scope>test</scope>
    </dependency>
