kad: impl Display on QueryId

[stormshield-frb]

Description

Currently, only Debug is implemented on protocols::kad::src::query.rs::QueryId. It would be great to also add a Display implementation for logging purposes, for example.

Motivation

For logging purposes, we would like to get (using tracing) something like query_id=3 instead of what is currently done query_id=QueryId(3).

Indeed, since only Debug implemented, we currently have to do debug!(?query_id, "Got a query") which render query_id=QueryId(3).

We would like to be able to do debug!(%query_id, "Got a query") to get query_id=3 which would be shorter and cleaner.

Requirements

1. implement std::fmt::Display on protocols::kad::src::query.rs::QueryId: format!("{}", QueryId(3)) should return "3".
