feat(torch): add new metric to expose the consensus nodes ids

[tty47]

hello!

This PR adds a new metric to expose the consensus nodes ids.

as a result, we will have something like:

# HELP consensus_node_ids_metric Metric for Consensus Node IDs
# TYPE consensus_node_ids_metric gauge
consensus_node_ids_metric{namespace="robusta-torch-1",node_id="190da74cda99235421a8df1e3b412e9902800a38",node_name="consensus-full-1",otel_scope_name="torch",otel_scope_version=""} 1
consensus_node_ids_metric{namespace="robusta-torch-1",node_id="321531224ce99495ceba205e56dd955b8fcdbbb0",node_name="consensus-validator-1",otel_scope_name="torch",otel_scope_version=""} 1

In Grafana, I have added this table, so it will help our teams:

cheers! 🚀

I have also added to this PR the log level and a custom format to see the file name and line in the logs, example:
