title: Configure OmniAuth logger to two different loggers depending the level of the error
body: <p>In my Rails 5 app I have <code>'omniauth', '~&gt; 2.0.3'</code> where in my config  <code>config/initializers/omniauth.rb</code> I'm attaching the logger to the <code>Rails.logger</code>.</p>
  <p><code>OmniAuth.config.logger = Rails.logger</code></p>
  <p>What I want to do is if the log level is <code>error</code> I want to use Rollbar instead of the Rails logger.</p>
  <p>Is there a way to do this?</p>
