Logs and metrics by peers

[KaloyanTanev]

🎯 Problem to be solved

Sometimes peers stop providing logs and we don't acknowledge it until we need the logs. It'd be nice to track if an operator is supplying logs and metrics from different parts of the stack. It'd also be nice to have an overview in the aggregate of how many peers are supplying in the cluster.

🛠️ Proposed solution

Per cluster

| peer   | Charon Metrics | Charon Logs | BN Logs | MEV Metrics | MEV Logs |
|--------|----------------|-------------|---------|-------------|----------|
| peer-1 |      ✅        |      ✅      |   ❌    |      ❌     |     ✅    |
| peer-2 |      ✅        |      ✅      |   ✅    |      ❌     |     ❌    |

Aggregate

| cluster   | Charon Metrics | Charon Logs | BN Logs | MEV Metrics | MEV Logs |
|-----------|----------------|-------------|---------|-------------|----------|
| cluster-1 |      7/7       |     5/7     |   3/7   |     0/7     |    3/7   |
| cluster-2 |      3/4       |     2/4     |   0/4   |     0/4     |    0/4   |
