what

• Update IAM permissions in Codebuild policy to allow running in a VPC
• Add a test using VPC config
• Change test region to us-east-2
• (There is probably a more elegant way to check if var.vpc_config is an empty object but I didn't find one in the time I spent looking.)

why

• The module supported setting VPC config on the Codebuild project, but the IAM permissions in the Codebuild policy were not sufficient

references

• None
