Pingora compatibility

[ThomasCartier]

Hi, Trying to implement websocket handling inside Pingora (instead of proxying -> some cases are better handled at the network edges without a local server that would handle the websocket part and reply to Pingora).

I understand that I can use this project src folder to parse the frame and handle the fragmentation, except handshake.rs and upgrade.rs, which are hyper/axum specific (UpgradeFut..).

I will look into it this week end but I wanted to have another opinion before I dive in.

Thanks guys
