Upgrade tokio to 1.22.0 and replace async-std with tokio #12646

Resolves #12499.

Doesn't work yet, because the tests rely on async-std being used. Converted into draft.

Overall LGTM but I have two questions:

is there a reason why async_std::spawn in tests is not converted to tokio::spawn?
the example code in rust-libp2p repository instructs to configure executor for the swarm in tokio chat example. Should we configure the default executor similarly in case params.executor is None in service.rs?

I'm paranoid about the second bullet because I burned two weeks debugging bizarre async execution issues after having configured libp2p incorrectly.

Nice! 👍

We should completely nuke async-std so that it isn't used anywhere in our codebases. Doesn't really make sense to have two different executors, especially when tokio's solid.

Interestingly, the PR libp2p/rust-libp2p#3097 has just landed in libp2p that makes the specification of executor explicit during the construction of Swarm: SwarmBuilder::new has been replaced with SwarmBuilder::with_executor + some alternative constructors with predifined executors for tokio, async-std, etc.

I'm going to change the API of NetworkWorker::new so it won't accept None executor anymore in this PR, and later when libp2p-0.50 is released we can move to the new SwarmBuilder::with_executor constructor.

I suspect that I have converted some futures::executor::block_on into runtime.block_on where it wasn't strictly necessary. I also don't like that in some tests we create tokio runtime explicitly and split sync initialization and async execution, and in others we just run everything under #[tokio::test]. So, may be a follow-up PR/commits are needed to clean these things up @altonen @bkchr.

libp2p 0.50 was released last week. here is the PR that updates substrate: #12734

let me know if you want me to change executors to tokio.

 	sp_tracing::try_init_simple();

-	let mut net = BeefyTestNet::new(2);
+	let runtime = Runtime::new().unwrap();


dummy question: can't we just use #[tokio::test]?

We can. I think, historically some tests were synchronous and later converted to async ones with manual runtime instantiation, and I just repeated the mistake and did the same in other places. Probably this doesn't make sense, so I'm going to convert all these tests to #[tokio::test] in a follow-up PR.

I hope we can get rid of all these block_on calls in the future in some follow-up PR
