Add timeouts

[tbraun96]

The option to timing out the test should be a parameter. E.g.,:

#[timeout(Duration::from_millis(1000))]
fn test_apple() {

}

When async is detected, a timeout future can be wrapped around the test itself, terminating if it times out.

Ok... I guess you can use ntest crate and combine it with rstest but as far I can see ntest don't support async tests.

Anyway I can try to introduce this feature in rstest. I'm not an expert but I guess that aync timeout depend from which runtime do you use and this can be very tricky to handle.

You can make timeouts runtime-agnostic: https://docs.rs/futures-timer/latest/futures_timer/index.html

Ok, I wrote a proof of concept
https://gist.github.com/la10736/6a3652c12d065d0201e36b3fc97f1caf#file-test_timeout-rs

But before start I need to refactor the project to split procedural macro crate from utility functions.

@la10736 Timeout doesn't seem to work with async fixtures:

    #[rstest]
    #[timeout(std::time::Duration::from_secs(100))]
    #[tokio::test(flavor = "multi_thread", worker_threads = 2)]
    async fn test_sanity_flow(#[future] service: EchoService) {
        let _ = service.await;
        assert_eq!(1, 1);
    }

error:

196 |     #[rstest]
    |     --------- captured by this `Fn` closure

Ok... I missed it in my test :(

Can you open a new ticket for this bug/limit?

I've just forget to close this ticket before.
