Cleanup elasticsearch related config

Remove elasticsearch01 as it has been turned off.

Allow all elasticsearch running nodes to talk to each other over ports
9200 to 9400. This includes the logstash-worker nodes running non data
elasticsearch clients. This appears to be necessary to keep logs from
filling up with gigs of NoRouteToHost exceptions on the worker nodes.
