In source code, de-obfuscate base64 AWS user data code that's deployed to EC2 instances

[mdorn]

There's no need to commit base64 data in source code, and doing so makes it unreadable to project developers - it can be converted to base64 before infrastructure deployment. For an example of how to deal with this, see this commit: See how _files/data/user_data_1.sh is legible, and translated to base64 during the Pulumi deploy process.
