Amazon released [HTTP APIs](https://aws.amazon.com/blogs/compute/announcing-http-apis-for-amazon-api-gateway/) for their api gateway product fairly recently, and I'd like to use Terraform to spin some up. I saw that Terraform has [documentation](https://www.terraform.io/docs/providers/aws/r/apigatewayv2_api.html) for the `aws_apigatewayv2_api` resource, which will create the gateway itself, but I can't find documentation for routes, stages, or any other types of resources that I'll be needing in my gateway.

Are HTTP APIs just not fully supported by Terraform yet, or am I missing some documentation somewhere?
