Packer Based Amazon ECS AMI

This is heavily based on the official our AWS Batch AMI repo.

Building

• Ensure you are logged into AWS (or have credentials setup so the CLI can use them)
• Ensure you have packer installed (see .tool-versions in the repo for the version to use)
• build with REGION=us-east-2 make build (be sure to change the REGION setting as needed for your use case)
