title: services.yml and path to file in same bundle
body: <p>How do i refer to a data file in the services.yml, which is located in the same or any bundle?</p>
  
  <p>Im shipping a csv-file which i would like to inject as argument.<br>
  It works when i use the direct path:</p>
  
  <pre><code>mybundle.data.csv: %kernel.root_dir%/../vendor/mybundle/my-bundle/mybundle/MyBundle/Resources/data/data.csv 
  </code></pre>
  
  <p>This is pretty verbose and unflexible and thus i am looking for a resolver like:</p>
  
  <pre><code>data.csv: "@MyBundle/Resources/data/data.csv"
  </code></pre>
  
  <p>But this is not working:</p>
  
  <blockquote>
    <p>... has a dependency on a non-existent service
    "mybundle/resources/data/data.csv".</p>
  </blockquote>
  
  <p>any ideas? </p>
