Control the subnet that an instance is started in

* Specify the Subnet that an instance is in
* Specify SecurityGroupIds (you can't use security group names with the
  non-default VPC)
* Specify whether instance should have a public IP assigned (by default
  in the non-default VPC this is not the case)

Instead of using an A record to the public IP of the instance, this pull
request adds the option to configure the Route53 to point to the public
DNS hostname (CNAME) instead.
Fix the CNAME record to point to the dns_hostname

Also use the configured TTL. I think missing this out causes Route53 to
get confused when you remove and add record sets
