Unit: io_uring support

[lolgab]

Do you plan to add support for io_uring on Linux kernels that support it?
It can be used as drop-in replacement for epoll but leveraging all its capabilities means re-writing all the reads/writes/accepts/(etc...) in an asynchronous fashion.
If NGINX Unit will support io_uring it will be a huge selling point in the next years!

Yes, it's planned.
