What this post added

This post details how to manage the GitLab agent for Kubernetes itself using GitOps principles. It covers turning an agent installation to manage itself by using kustomize overlays with sealed secrets for authentication tokens, and adopting the agent by the agent using inventory policies. It also outlines how to automate the hydration of manifests using GitLab CI/CD and how to upgrade agentk versions by simply bumping the version number in code.
