Add support for io_uring

[skbeh]

This only works when not using unix domain socket and compression is disabled because the netty io_uring transport does not support unix domain socket and the client can not decode compressed packets sent with io_uring.

Disable this by default

@MachineBreaker Done.

Hello, thanks for the pullrequest, however, we decided not to add support for IO_URING for now as it is an experimental feature and for security reasons as Kenny said here.

What's not secure with this solution? I heard that io_uring brings great performance.
