Elasticsearch logs show Did you forget to close a response body

Issue

The logging-elasticsearch pods have a lot of this message:

WARNING: A connection to https://10.101.16.1/ was leaked. Did you forget to close a response body? To see where this was allocated, set the OkHttpClient logger level to FINE: Logger.getLogger(OkHttpClient.class.getName()).setLevel(Level.FINE);
