Generic windows template to build an AMI using packer and the amazon-ebs builder. The following variables need to be passed from the environment/CI server:
assume-role.sh contains a sample script for assuming a cross account IAM role that can be used to launch the builder instance in another account, it will set the AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_SESSION_TOKEN variables.
In addition the host running packer needs a validator secret key available, the path is currently hardcoded in the template.
