Added the start of the terraform piece for air-gap development.

docs/airgap/developer/terraform/README.tf

+Terraform that creates a new VPC and two subnets. One subnet is public the other is airgapped except for access to/from the public subnet. This allows for a jump box or other resources to be easily moved in and out of the public subnet for setting up your development environment for the private subnet.
