title: Parse multiline logs as a single event in Fluentd
body: <p>We have EFK implemented on Openshift Container Platform version 4.3.</p>
  <p>Issue:
  Multiline logs such as Java Stack trace, SQL queries are not getting parsed as a single event in Fluentd and because of this we are getting multiple entries in Kibana.
  We need to parse multiline logs as a single event, so that we get a single entry in Kibana for an exception or SQL query.</p>
