Feature Enhancement: Http2 keep alive probes

[TTurletti]

Description:

Adding the http2_protocol_options in envoy gateway to manage http2 keepalive in ClientTrafficPolicy

    http2_protocol_options:
      connection_keepalive: {
        interval: 60s,
        timeout: 10s,
        connection_idle_interval: 10s

Hi @arkodg @zirain

I’ve started looking into this and wanted to share my current understanding and proposed approach to make sure I’m aligned before opening a PR.

From what I see, this would involve exposing http2_protocol_options.connection_keepalive via ClientTrafficPolicy, and then wiring that through the translator so the generated Envoy config sets the corresponding HTTP/2 keepalive fields (interval, timeout, idle interval).

I’m currently checking how similar protocol options are handled in the codebase to follow existing patterns and avoid introducing API inconsistencies.

If this approach sounds reasonable, I’m happy to proceed with an implementation and open a PR. Feedback welcome.

Thanks!

@Aditya7880900936 love the interest youre showing in the project and the time youre spending to understanding the details, my recommendation would be to pick 1 GH issue at a time and take it to completion before picking another issue up

Thanks for the guidance, @arkodg — that makes sense.

I’ll focus on this issue and take it through to completion before picking up anything else. I’m continuing to dig into the translator and related protocol options to make sure the implementation aligns well with existing patterns.

I’ll share updates or a draft PR once I have something concrete.

Appreciate the feedback!
