Adding Kubvernor to the list of implementors

[dawid-nowak]

Kubvernor Rust API Gateway is an open-source, highly experimental implementation of API controller in Rust programming language. Currently, Kubernor supports Envoy Proxy. The project aims to be as generic as possible so Kubvernor can be used to manage/deploy different gateways (Envoy, Nginx, HAProxy, etc.). Kubvernor Rust API Gateway implements Inference Extensions v0.5.1.

Hi @dawid-nowak. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

pretty please, could we move it forward...

This PR follows what we have been doing up to this point as a project (implementation-specific guides), but per #1502 we likely need to start moving away from that. Given that we already have this level of content for many other implementations, it could be viable to accept this as is and then immediately work to retract implementation-specific content more broadly.

@liu-cong @nirrozenbaum @danehans Don't leave me hanging 😃
Given Rob's comment above... Could we get it acepted or rejected?

+1 on this. Deferring to @danehans and @nirrozenbaum to make the call

[danehans]

A user should not be required to install Rust to deploy a GIE gateway. Common deployment tools such as kubectl, Helm, etc., should be the only requirement for a user to deploy.

[danehans]

All required steps should be captured here instead of an external link

Note: Due to #1502, we plan on removing most 3rd party content from the docs site. We will instead refer to the implementations page. Conformant implementations will be required to maintain their own install guides.

This is a good example of why https://github.com/kubernetes-sigs/gateway-api-inference-extension/pull/1313/files#r2316592252.

Yeah, but that would potentially make this page even more unreadable. And even for GKE there is a link to external docs. Perhaps it is ok to proceed as is. Given that this is going to change anyway.
