title: Startup scripts in GCP deployment manager
body: <p>I'm deploying a VM instance using GCP deployment manager. There are some initialization actions which should be executed over deployment process.
  I have imported a startup script and added the <code>metadata-from-file</code> property following this example: 
  <a href="https://github.com/GoogleCloudPlatform/deploymentmanager-samples/blob/master/examples/v2/metadata_from_file/jinja/config.yaml" rel="nofollow noreferrer">https://github.com/GoogleCloudPlatform/deploymentmanager-samples/blob/master/examples/v2/metadata_from_file/jinja/config.yaml</a></p>
  
  <p>But I don't see those actions getting executed. Any other way to have such scripts included in the deployment plan?</p>
