Change subject: Configure elasticearch multicast per datacenter
......................................................................
Configure elasticearch multicast per datacenter
In production each datacenter will get its own elasticsearch multicast
group and its own cluster name. There should be no chance of a machine
from one datacenter joining a cluster in another one accidentally.
