It is currently assumed that the elasticsearch data nodes and the logstash nodes are co-located within the same container during deployment of the ELK stack. This commit is intended to remove that assumption by requiring specification of separate elastic and logstash groups. This is particularly important where instances of elasticsearch and logstash are separated for resource reasons, a common setup for an elastic cluster. The default setup for the elastic nodes has been simplified, with all non-coordinating nodes being both data and ingest nodes unless otherwise specified. This was previously defined algorithmically, with the elastic node setup tightly coupled to the placement of the logstash instances. Change-Id: Id06eb78b52705aefea9cfe1247f53bac58badd52
