Review PeerDAS Metrics

[lucassaldanha]

Reference: ethereum/beacon-metrics#14
Dashboard: https://github.com/ethpandaops/ethereum-package/blob/main/static_files/grafana-config/dashboards/peerdas-dashboard.json

Tasks:

• Verify what metrics we are missing
• Implement missing metrics

Note: we had this issue Nashatyrev#65 that seems to have been forgotten.
