title: Can't set AWS Elastic Beanstalk static path with config file
body: <p>I have a <code>config</code> file in my projects's <code>.ebextensions</code> directory containing</p>
  
  <pre><code>option_settings:
    "aws:elasticbeanstalk:container:python:staticfiles":
      "/static/": "sitetest/static/"
  </code></pre>
  
  <p>but my EB environment does not change the setting for <code>/static/</code> in response to this being pushed to AWS.</p>
  
  <p>I can verify that other <code>config</code> settings in the same directory — e.g. for environment variables using</p>
  
  <pre><code>option_settings:
    "aws:elasticbeanstalk:application:environment":
      SOME_VAR: "foo"
  </code></pre>
  
  <p>or for container commands using</p>
  
  <pre><code>container_commands:
    00_syncdb:
      command: "python manage.py db upgrade"
      leader_only: true
  </code></pre>
  
  <p>behave as expected.</p>
  
  <p>Why isn't AWS Elastic Beanstalk's static path changing when to correspond to the setting in my config file?</p>
