      region - the AWS region name
      bucket - the S3 bucket name.  The bucket gets created if it does not exist.
      keyPrefix - the S3 key prefix to be used for each log export to S3, 
        e.g., logs/<stackname> where <stackname> is the name of the CloudFormation
              stack associated with the root template for a given deployment.
              The root stack name is unique.
              Using logs as the beginning of the prefix keeps all logs in a 
              separate "folder" of the bucket.
      fqdn - fully qualified domain name of the node exporting the logs
             The FQDN provides uniqueness as there may be more than one node 
             with a given role.
