[LIBP2P] - Integrate Metrics `NetworkBehaviour` to libp2p

[bfish713]

What is this task and why do we need to work on it?

Libp2p provides a metrics behaviour which can automatically collect some stats for us.

Docs: https://docs.rs/libp2p/latest/libp2p/metrics/index.html Examples: https://github.com/libp2p/rust-libp2p/tree/master/examples/metrics

This should play nicely with our use of tracing, and we can enable the interesting spans in our test environment to try to figure out issues/bottlenecks.

We don't need to create an http service for the metric collections, I think we can just log them for now.

Follow up will be to integrate with the HotShot Metrics
