Support terraform 0.13

[ipmb]

When running the 0.13 beta, I get the following error:

Error: Unsupported Terraform Core version

  on .terraform/modules/client_vpc/terraform-aws-vpc-2.38.0/versions.tf line 2, in terraform:
   2:   required_version = "~> 0.12.6"

Module module.client_vpc (from terraform-aws-modules/vpc/aws) does not support
Terraform version 0.13.0-beta1. To proceed, either choose another supported
Terraform version or update this version constraint. Version constraints are
normally set for good reason, so updating the constraint may lead to other
errors or unexpected behavior.
