Implement tracker error timeout

[Awkor]

Let me know if you think the approach is valid or if there's something you would like to be changed (e.g. variable names).

I still need to add the documentation comments.

I tried compiling the test CLI to run the integration tests but I got the following error:

error[E0599]: the method `next` exists for struct `tokio::sync::mpsc::unbounded::UnboundedReceiver<cratetorrent::alert::Alert>`, but its trait bounds were not satisfied
  --> src/main.rs:72:38
