Description

### What problem are you trying to solve?

As the control plane ships with prometheus, it would be possible to include some out of the box alerts (just like the Grafana dashboards). These can be both per-service and per-route for all the golden metrics. The control plane can ship with the alerts configured and all a user would need to do is configure their preferred channel.

### How should the problem be solved?

- Alertmanager as an install option.
- Default alerting policy for the control plane.
- Simple configuration of alert channels (slack, email).
- Integration with ServiceProfiles to provide alerting rules for Alertmanager.

Research direction

Start by reviewing the control plane's existing Prometheus integration, Grafana dashboards, and ServiceProfiles support. Define the scope for an Alertmanager install option, default control-plane policy, Slack and email channel configuration, and ServiceProfiles-based alert rules; done means these requirements are integrated as a coherent, documented feature.
