Continuous Deployment of Grafana Dashboards

[LanaKast]

As a administrator, I want to automatically update the Grafana dashboards once a new version of the dashboard is pushed to a git repository. A set of Jsonnet templates (called Grafonnet) can be used to quickly and easily write dashboards programmatically. The versioning system should allow us to keep track of changes.

Acceptance critera:

• [ ] Dashboards are configured in git
• [ ] After deployment, the Dashboard is available in Grafana
