Notice when a new image is available for deployment

Problem Statement

As an Application Operator, I want to be alerted when a new version of an image is available for deployment, so I can assure that I'm on the preferred version in my cluster.

• Preferred version: we should support semantic versions probably
• Smart updates:
  • the update could happen automatically or manually, depending on configuration
  • the update could happen based on image digests, and only the changed images are deployed and restarted

1. A new version of the image is pushed to the docker registry
2. An issue/MR is raised to update the manifests to the most recent version.
3. The changes are applied directly to the git repo
