title: One Jenkinsfile for multiples repositories
body: <p>I want to have 1 main repository with some common configurations to be used:</p>
  <pre><code>Common
     ---&gt; jenkinsfile
     ---&gt; x.json
     ---&gt; config.json
  </code></pre>
  <p>I would like to have different teams to be able to use that common repo and just create their own repos with their specific additional code:</p>
  <pre><code>Team1 repo
    sub1/
    ---&gt;x.json
    ---&gt;config.json
    sub2/
    ---&gt;x.json
    ---&gt;config.json
  
  Team2 repo
    ---&gt;x.json
    ---&gt;config.json
  </code></pre>
  <p>Is there a possibility to have this centralized Jenkinsfile to be used by the different teams without explicitly putting it in their respective repositories?</p>
  <p>thank you.</p>
