Netty: IO_URING as epoll alternative

[gliwka]

Since Linux 5.1 there’s a new mechanism for high-performance batched asynchronous IO called io_uring. While it was primarily designed for disk io, it also works for network requests: https://blog.cloudflare.com/io_submit-the-epoll-alternative-youve-never-heard-about/

Is this something that would make sense for netty?

@gliwka yes! In fact its something I plan to do if its not done as part of GSOC:

Is it happening as part of GSOC still @normanmaurer?
