The tokio::net::udp module is empty

[Darksonn]

The tokio::net::udp module is empty. Unless we add something to it during 0.3, we should remove it for 1.0.

The contents are currently commented out pending the results of #2830. I'd personally like to see tokio include first class UDP support in the v1.0 milestone

edit: Wow, sorry, I misunderstood the comment to be about tokio-util. AFAIK OwnedReadHalf OwnedWriteHalf etc are not necessary for UdpSocket because you can just Arc it and be on your way?

[LucioFranco]

Okay I think the right approach here is to pub(crate) the udp module and to bring it back in later iterations. We likely can put most of the things in there into tokio_util::udp.

[Darksonn]

Yeah, just remove the module for now. We can add it back if we added read and write halfs or some other udp utility.

I had a branch that added the read/write halves but removed it because you can just use Arc. If you want to include the read/write halves anyway though, let me know and I can polish it up. In the meantime I can remove the module.
