This is an EC2 clustering strategy for  [libcluster]( It currently supports identifying nodes based on EC2 tags.

The default `Tags` strategy uses [ex_aws]( to query the EC2 DescribeInstances API endpoint. Access to this API should be granted to the EC2 instance profile. See the ExAws docs for additional configuration options.
