Type of change:

• Bugfix
• New feature provided
• Improve performance
• Backport patches
• Documentation
• Refactor
• Chore
• CI/CD or Tests

What this PR does / why we need it:

By default, static configuration will prevail, and the deployment mode of the data plane can be dynamically specified.
mode: apisix or mode: apisix-standalone

apiVersion: apisix.apache.org/v1alpha1
kind: GatewayProxy
metadata:
  name: apisix-proxy-config
spec:
  provider:
    type: ControlPlane
    controlPlane:
      mode: apisix # apisix-standalone
      service:
        name: hello
        port: 9180
      auth:
        type: AdminKey
        adminKey:
          value: "%s"

Pull Request Overview

This PR adds support for multi-mode APISIX deployments by introducing a mode field to the GatewayProxy CRD. This allows individual gateway proxies to specify whether they use apisix (with etcd) or apisix-standalone (with yaml configuration) mode, independent of the global provider type setting.

Key changes:

• Added mode field to ControlPlaneProvider in the GatewayProxy API and CRD
• Refactored provider options to use "Default" prefix to distinguish between default and per-gateway settings
• Added BakcnedType field to Config struct to carry mode information per gateway
• Created test case for multi-mode deployment scenarios
