Operations: Release Deployment

The release deployment is an automated process which tracks the following steps:

1. human: Create a GitHub Release
2. bot: Build a container image from the release
3. bot: Push container image to GitHub packages
4. bot: Generate manifest files to deploy release
5. bot: Publish manifest files to GitHub release
6. bot: Open Pull Request into releases/v1 from develop
7. bot: Comment on PR showing changes to be applied by deployment
8. human: Approve/merge release
9. bot: Download manifest files from GitHub release
10. bot: Apply manifest files for release to cluster

The automated portions are implemented in .github/workflows/infra-release.yml and .github/workflows/infra-deploy.yml
