Graceful shutdown hangs when I use a Chromium based browser

[czy-29]

This problem of Viz is exactly the same as Axum:
tokio-rs/axum#2611

This is due to a bug in hyper-util:
issue: hyperium/hyper#3576
pr: hyperium/hyper-util#101

Patching hyper-util in Cargo.toml like this also works for viz:

[patch.crates-io]
hyper-util = { git = "https://github.com/hyperium/hyper-util.git", rev = "a77d866ff65a68ea5d048d058108552c39ec470d" }

The reason for posting the same issue here in Viz is that when hyper-util is finally updated, I hope we can follow up with the updated version in time, so that I can remove such a temporary patch and update to the latest version.

Thanks for the feedback. I will fix this ASAP.

hyper-util 0.1.4 is released!
https://crates.io/crates/hyper-util/0.1.4
We should update as soon as possible and finally close this issue.

Nice! Let's ship it.
