v0.10.0

Pass dns_name to terraform-aws-route53-cluster-hostname instead of name @michael-careplanner (#24)

what

• Fixes incorrect DNS records when setting custom records in R53 by passing dns_name rather than name to terraform-aws-route53-cluster-hostname

why

• terraform-aws-route53-cluster-hostname changed how to pass the DNS name in between 0.5.0 and 0.7.0+
• In 0.5.0 the DNS record was created used var.name (https://github.com/cloudposse/terraform-aws-route53-cluster-hostname/blob/0.5.0/main.tf#L4) - which is what this module passes.
• Since 0.7.0 the DNS record created uses var.dns_name if set, defaulting to module.this.id if not (https://github.com/cloudposse/terraform-aws-route53-cluster-hostname/blob/0.7.0/main.tf#L3)
• This results in the custom DNS names passed in this module not generating the correct R53 records.
