Rust ControlPlane: GatewayClass Controller

[shaneutt]

The purpose of this task is to create a GatewayClass controller in Rust. This controller is very simple, pretty much only marking the GatewayClass as accepted or not based on ControllerName.

See the Go version of this for reference: https://github.com/kubernetes-sigs/blixt/blob/archive/golang-control-plane/controllers/gatewayclass_controller.go

TODO

• Create a GatewayClass controller that marks managed GatewayClass resources as accepted
• Update the Gateway controller to verify that any GatewayClass is accepted before programming routes
• Add integration tests for GatewayClass and Gateway which mirror our previous Golang-based tests

I am a beginner in Rust. If possible, I'd like to give it a try.

Thank you @nayihz but at the moment this one already has an owner and is in progress. Please feel free to check out other issues which don't have assignees, and in general if you're just starting Rust but you'd like to do something practical, I can definitely recommend the Rust By Example Book!

I also strongly the "Rust in 4 Days" course by the google android team: https://google.github.io/comprehensive-rust/ I worked through that (admittedly over more than 4 days) before touching anything in this code base. Best Evan Jones Website: www.ea-jones.com

@shaneutt Happy new year 🥳

Is there any other validation we should perform prior to acceptance?

I ask because in the docs there's an example of a failed acceptance state, but the docs are unclear about the conditions that might lead to failure.

[shaneutt]

We should try to do the following to validate the work here:

1. run any tests that are relevant in the Golang test suite and see if they're still passing.
2. validate any behaviors covered in the Gateway API conformance test suite

That said, as always with this project it's reasonable to take an iterative approach. If we can get some chunk done in one PR that has some of the validation we want, and is written in a way that is poised for additive iterations towards something more complete, that's fine too.

Okay, I'll look at number 2 as the golden spec. Thanks.
