Elasticsearch can be used as a smart load balancer for all traffic
which will remove the requirement for a VIP and move the cluster to a
mesh topology. All of the Kibana nodes will now run elasticsearch as
cordonator.
* Kibana will now connect to elasticsearch on localhost.
* All of the beats have been setup to use use the new mesh topology.
* jvm memory management has been updated to reflect the additional
services.
More on node assigments can be found here:
* https://www.elastic.co/guide/en/elasticsearch/reference/6.2/modules-node.html#modules-node
* The readme has been updated to reflect these changes.
