title: Apache Airflow - customize logging format
body: <p>Is it possible to customize the format that Airflow uses for logging?</p>
  
  <p>I tried adding a LOG_FORMAT variable in $AIRFLOW_HOME/airflow.cfg, but it doesn't seem to take effect</p>
  
  <pre><code>LOG_FORMAT = "%(asctime)s logLevel=%(levelname)s logger=%(name)s - %(message)s"
  </code></pre>
