Logging-Kibana Pod Runs Out Of Memory

Issue

• Noticed that the kibana container, within the logging-kibana pod keeps going OOM, and restarting every 1.5-2 hours.
• It looks like a new environment variable KIBANA_MEMORY_LIMIT was added to the dc/logging-kibana deployment configuration. It appears to be setting the memory to 736 MB.
• Kibana pod is terminating with exit code 137 (OOMKilled)
