This tiny PR adds the query ID to some kademlia log messages from the FIND_NODE and GET_RECORDS commands.

Used to provide better debug information and upgrade a few missing states from trace to warn.

Looks good. However just to make sure, these warn messages should not appear during normal operation right? Just to make sure that they will not spam the logs.

Initially wanted to expose the info better to our triaging. However, this is not something critical atm and we could probably better add this as a metric in the future:

Have downgraded this to debug, thanks!

chore: Release litep2p 0.7.0 (#240)
a68b713 
## [0.7.0] - 2024-09-05

This release introduces several new features, improvements, and fixes to
the litep2p library. Key updates include enhanced error handling,
configurable connection limits, and a new API for managing public
addresses.

### [Exposing Public Addresses
API](#212)

A new `PublicAddresses` API has been added, enabling users to manage the
node's public addresses. This API allows developers to add, remove, and
retrieve public addresses, which are shared with peers through the
Identify protocol.

```rust
    // Public addresses are accessible from the main litep2p instance.
    let public_addresses = litep2p.public_addresses();

    // Add a new public address to the node.
    if let Err(err) = public_addresses.add_address(multiaddr) {
        eprintln!("Failed to add public address: {:?}", err);
    }

    // Remove a public address from the node.
    public_addresses.remove_address(&multiaddr);

    // Retrieve all public addresses of the node.
    for address in public_addresses.get_addresses() {
        println!("Public address: {}", address);
    }
```

**Breaking Change**: The Identify protocol no longer includes public
addresses in its configuration. Instead, use the new `PublicAddresses`
API.

Migration Guide:

```rust
    // Before:
    let (identify_config, identify_event_stream) = IdentifyConfig::new(
        "/substrate/1.0".to_string(),
        Some(user_agent),
        config.public_addresses,
    );

    // After:
    let (identify_config, identify_event_stream) =
        IdentifyConfig::new("/substrate/1.0".to_string(), Some(user_agent));
    // Public addresses must now be added using the `PublicAddresses` API:
    for address in config.public_addresses {
        if let Err(err) = public_addresses.add_address(address) {
            eprintln!("Failed to add public address: {:?}", err);
        }
    }
```

### [Dial Error and List Dial Failures
Event](#206)

The `DialFailure` event has been enhanced with a new `DialError` enum
for more precise error reporting when a dial attempt fails.
Additionally, a `ListDialFailures` event has been introduced, listing
all dialed addresses and their corresponding errors when multiple
addresses are involved.

Other litep2p errors, such as `ParseError`, `AddressError`, and
`NegotiationError`, have been refactored for improved error propagation.

### [Immediate Dial Error and Request-Response Rejection
Reasons](#227)

This new feature paves the way for better error handling in the
`litep2p` library and moves away from the overarching
`litep2p::error::Error` enum.

The newly added `ImmediateDialError` enum captures errors occurring
before a dial request is sent (e.g., missing peer IDs). It also enhances
the `RejectReason` enum for request-response protocols, offering more
detailed rejection reasons.


```rust
match error {
    RequestResponseError::Rejected(reason) => {
        match reason {
            RejectReason::ConnectionClosed => "connection-closed",
            RejectReason::DialFailed(Some(ImmediateDialError::AlreadyConnected)) => "already-connected",
            _ => "other",
        }
    }
    _ => "other",
}
```

### [Connection Limits](#185)

Developers can now set limits on the number of inbound and outbound
connections to manage resources and optimize performance.

```rust
    // Configure connection limits for inbound and outbound established connections.
    let litep2p_config = Config::default()
        .with_connection_limits(ConnectionLimitsConfig::default()
            .max_incoming_connections(Some(3))
            .max_outgoing_connections(Some(2))
        );
```

### [Feature Flags for Optional
Transports](#192)

The library now supports feature flags to selectively enable or disable
transport protocols. By default, only the `TCP` transport is enabled.
Optional transports include:

- `quic` - Enables QUIC transport.
- `websocket` - Enables WebSocket transport.
- `webrtc` - Enables WebRTC transport.

### [Configurable Keep-Alive
Timeout](#155)

The keep-alive timeout for connections is now configurable, providing
more control over connection lifecycles.

```rust
    // Set keep alive timeout for connections.
    let litep2p_config = Config::default()
        .with_keep_alive_timeout(Duration::from_secs(30));
```
