Title: 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)
