title: Template file is not a valid location in Gitlab CI/CD
body: <p>I've modified my Gitlab CI/CD current process to add a stage about the code quality using codeclimate. I've tried to follow Gitlab doc as possible as I can, nevertheless I got an error about the configuration template.</p>
  <pre><code> .codeclimate.yml is not a valid location!
  </code></pre>
  <p>Here is the content of my <code>.gitlabci.yml</code> file</p>
  <pre><code>include:
   - template: .codeclimate.yml
  
  stages:
    - slack-start-prod
    - slack-start-staging
    - docker
    - test
    - code-quality
    - deploy-staging
    - deploy-prod
    - slack-end-prod
    - slack-end-staging
