Is your feature request related to a problem? Please describe.

We do not test http tunneling (https://github.com/solo-io/gloo/blob/main/test/e2e/http_tunneling_test.go) using proxy protocol. Testing with the the same tunneling proxy impl I see:

1) With TLS: OPENSSL_internal:WRONG_VERSION_NUMBER 2) Without TLS: Sending local reply with details http1.codec_error

I suspect this is an issue with the tunneling proxy impl we test against: https://github.com/solo-io/gloo/blob/main/test/e2e/http_tunneling_test.go#L402

Describe the solution you'd like

Add a test for http tunneling with proxy protocol and resolve any issues

Describe alternatives you've considered

The full requirement is PP through this entire chain: Client -> tunneling proxy1 -> GE1 -> tunneling proxy2 -> GE2 -> service where the original client IP is transmitted via PP to the service.

https://github.com/solo-io/gloo/pull/8636/files an exampleof using proxy protocol on test proxy. Does not execute them with proxy protocol fully but should unblock the creation of a tunneling proxy example

Currently we do not support passing along a tcp proxy protocol to the target of our tunnel. However since it is http we can use http header. Is there any need for a tcp proxy protocol in this case?

[nfuden]

Since the customer asking for this was advised of cleaner ways to pass along ip info (headers) unassigning this issue
