Update FluentD Config for Increased Reliability

Test during the last few weeks has shown that violations- logs are not being sent in as periodically as they should be.

Restarting the pod logs get dumped and don't get sent in again until pod is restarted.

FluentD application and/or config may need to be updated with new/better Buffer settings to increase reliability of log ingestion.

Confirmed issue is happening even while opa-collector pod is able to communicate with both the cluster kube-api and Elasticsearch successfully.
