This is a third party library and should be abstracted away with its own package, including tests so it can be replaced if need be.

It seems to me that PROXY is a wrapper protocol like many others (e.g. websocket). We should consider creating a generic abstraction for wrapper protocols.

I don't foresee having any other wrapping protocols in-front of the ssh server since, we can consider that if it's necessary further down the line.

Please describe the change you are making
Implement support for the PROXY protocol. Sadly this cannot easily be tested as there are no user-visible changes if this is implemented correctly. (Header is transparently accepted/rejected)
