Investigate other `pingora` integrations

[James Munns]

It would be worth looking into existing integrators of pingora. This includes:

• The example proxy in the pingora repo
• This project seen on /r/rust: https://github.com/randommm/pingora-reverse-proxy

If anyone is aware of any other prior art, feel free to share here.

Closing this, as we've done necessary investigation.
