feat: Add Gateway API support for vmauth

[hkmdxlftjf]

Hello, I would like to add support for Gateway API in vmauth, so that it can recognize and work with Gateway and HTTPRoute resources, similar to how it currently handles Ingress.

I am interested in implementing this feature and contributing the changes to vmauth.

suppose it's a good feature, but not sure we need to manage gateway resource as well, httproute should be enough

Okay, I will only add management for httproute.

In my understanding, it only makes sense to introduce simplified version of HTTPRoute.

Something like:

kind: VMAuth
spec:
  httpRoute:
    parentRefs:
    - name: my-gateway
    hostnames:
    - my-vmauth.example.com    

Operator will render it and attach single rules targeting vmauth.

HTTPRoute support for VMAuth was added in operator v0.66.0 and released in helm chart 0.57.0
