Description

The elasticsearch rest appender sends data to elasticsearch with a refresh triggered:

client.performRequest("POST", endpoint, Collections.singletonMap("refresh", "true"), request); 

The problem is that the refresh result is cached in the Elasticsearch REST client, causing a bunch of useless HashMap.

The "auto-refresh" is not needed anymore and should be removed.
