title: Nuxt: choose client config other than default
body: <p>I'm using Nuxt and <a href="https://github.com/nuxt-community/apollo-module" rel="nofollow noreferrer">Nuxt-Apollo</a> to create my Vue application. I have the following apollo configuration in my <code>nuxt.config.js</code> file:</p>
  
  <pre><code>apollo: {
      clientConfigs: {
        default: {
          httpEndpoint: 'http://localhost:8000/graphql/'
        },
        stage: {
          httpEndpoint: 'https://example-stage.com/graphql/'
        }
        prod: {
          httpEndpoint: 'https://example.com/graphql/'
        }
      }
    }
  </code></pre>
  
  <p>How can I point to the <code>stage</code> or <code>prod</code> config. Every time I run the app it's pointing to the <code>default</code> config. There has to be somewhere I can set this.</p>
