Implement Argo CD

[Emterry]

Idea Description 

I envision it running inside the management cluster to control the deployments of data platform dev instances instead of github actions. Provides a GitOps style of deployment rather than being reliant on pipelines in many different repos to deploy apps. Argo cd provides constant updates a sync between our GitHub repo and environments.

Why Should We Do This 

Enhancing Security: Immediate alerts on potential deployment issues or security vulnerabilities.
Boosting Efficiency: Real-time insights enable quicker response, reducing downtime.
Improving Visibility: Teams gain a clearer understanding of deployment health.
Personal and Team Development: Working on this feature offers a chance to delve into advanced aspects of DevOps, improving our team's skills in monitoring and Kubernetes management.

Benefit all deployments are GitOps compliant - not currently as pipeline deploys helm chart which regularly fails
we can significantly improve the way teams interact with and manage their Kubernetes deployments

Definition of Done 

[ ] The monitoring system is fully integrated and can track key deployment metrics.
[ ] A successful demo has been conducted, showcasing the system’s functionality.

What skills do we need? 

Understanding of Kubernetes and CI/CD pipelines.
