LGTM. Just double check the env var before merging, I had the impression we used ES_ROLLOVER instead of ROLLOVER

[pavolloffay]

There is no ES_ROLLOVER anywhere. It's only ROLLOVER as those scripts work only for ES https://github.com/jaegertracing/jaeger/blob/master/plugin/storage/es/esCleaner.py#L19
