## Issue Addressed

N/A

## Proposed Changes

This PR adds the `msg` field to `Peer score adjusted` log messages. These `msg` fields help identify *why* a peer was banned.

Example:

```
Jan 11 04:18:48.096 DEBG Peer score adjusted                     score: -100.00, peer_id: 16Uiu2HAmQskxKWWGYfginwZ51n5uDbhvjHYnvASK7PZ5gBdLmzWj, msg: attn_unknown_head, service: libp2p
Jan 11 04:18:48.096 DEBG Peer score adjusted                     score: -27.86, peer_id: 16Uiu2HAmA7cCb3MemVDbK3MHZoSb7VN3cFUG3vuSZgnGesuVhPDE, msg: sync_past_slot, service: libp2p

```

There is also a `libp2p_report_peer_msgs_total` metrics which allows us to see count of reports per `msg` tag.
