🚀 Support for k8s.apisix.apache.org/headers and rewrite-uri annotations missing in v1.8.4

[m4dm4rtig4n]

Description

Bug / Feature Request

In APISIX Ingress Controller version v1.8.4, annotations related to the proxy-rewrite plugin are not complete when defined on an Ingress resource.

Environment

• APISIX Ingress Controller version: v1.8.4
• Kubernetes version: v1.28.x
• Installation method: Helm
• Mode: Ingress resource (not ApisixRoute)

Expected Behavior

When defining the following annotations on a standard Ingress, I expect them to configure the proxy-rewrite add/set/remove header automatically in the route created by APISIX:

annotations:
  k8s.apisix.apache.org/rewrite-target-regex: ^/api/authentication/(.*)
  k8s.apisix.apache.org/rewrite-target-regex-template: "/$1"
  k8s.apisix.apache.org/rewrite-target-add-header: X-Forwarded-For:$remote_addr
  k8s.apisix.apache.org/rewrite-target-set-header: "X-Api-Engine:apisix,X-Api-Version:v1,X-Api-useless:"
  k8s.apisix.apache.org/rewrite-target-remove-header: "Cookie"

JSON Configuration exemple needed:

{
  "uri": "/api/authentication/*",
  "name": "Auth",
  "plugins": {
    "proxy-rewrite": {
      "headers": {
        "add": {
          "X-Forwarded-For": "$remote_addr"
        },
        "remove": [
          "Cookie"
        ],
        "set": {
          "X-Api-Engine": "apisix",
          "X-Api-Version": "v1",
          "X-Api-useless": ""
        }
      },
      "regex_uri": [
        "^/api/authentication/(.*)",
        "/$1"
      ],
      "use_real_request_uri_unsafe": false
    }
  },
  "upstream_id": "or",
  "status": 1
}

Thanks for your great work!
