Script to flag GCP and AWS resources that are unexpected / wasteful

Created by: beyang

Is there a simple script we could write that does the following?

• query the GCP and AWS APIs for all compute resources tied to our billing account
• compare these against a git-vendored list of expected resources (e.g., resources associated with *.sgdev.org or sourcegraph.com)
• alert someone (or a Slack channel) when unexpected resources exist
