Nics are logical entities in Ubicloud which we use to configure TAP devices later on. In AWS, they are similar, but they also get the public IP addresses assigned. In Ubicloud, they are mostly related to private networking. Here in this commit, we introduce the logic to prepare an AWS network interface to be used by a VM. The only missing piece is the private IPv6 element. We'll skip that for now.
