Add Support for Stackrox CI Integration

Proposal

Red Hat Advanced Cluster Security for Kubernetes integrates into CI pipelines after images are built and pushed to a registry. Pushing the image first allows developers to continue testing their artifacts while dealing with any policy violations alongside any other CI test failures, linter violations, or other problems.

We should test deploying this tool and add documentation to support its integration. There's existing documentation for integrating this tool in CI systems but it doesn't cover GitLab currently.
