Description
Ec2Region sets a one-to-one mapping between the EC2 region name and the datacenter name. I'd like to be able to make the DC name configurable.
The use case here is running DataStax Enterprise in EC2 and the need to have a plain c* datacenter and a c*/solr cluster datacenter running within the same region (for the same cluster). Can't make the two (or more) datacenters in the region with the one-to-one mapping of EC2 region to c* DC.
