This changes updates the Fluentd to Elasticsearch collector to use a tag which has the format
kubernetes.<pod-name>-<container-name>
and it strips out the Docker image name and some of the previous prefix which was not useful. Once this is in I will update the corresponding collector for Cloud Logging which should result in nicer tag for searching the logs of a pod even after container restarts.
