Move away from Github Actions

[jim-sheldon]

Our Github Actions do work that would better be done using Batch or some AWS service; we would gain the benefits of terraform, logging, monitoring, etc. and consolidate our infrastructure to move closer to a day 0 turnkey package.

We should explore AWS CodeBuild, and move our non-build actions to Batch.

See #211 and #21.

This is for CI/CD? We should keep tests in GitHub Actions

[jim-sheldon]

AWS CodeBuild is CI/CD. I am open to trying things, but so far Github Actions appear to be strictly inferior to their AWS analogs.

Noting a bad silent failure of Github Actions that took way too long to find and fix.
