title: Rollbar ignore ActiveRecord::RecordNotFound exceptions
body: <p>I would like Rollbar to ignore uncaught exceptions <code>ActiveRecord::RecordNotFound</code> to save request pool in our plan. I did what they say in documentation:</p>
  
  <pre><code>config.exception_level_filters.merge!({
    "ActiveRecord::RecordNotFound" =&gt; "ignore"
  })
  </code></pre>
  
  <p>but Rollbar still reports the errors in the API. How do I filter out those exceptions?</p>
