有个问题想问下，gatewayproxy 引用的 secret 发生了变化，会触发 apisixglobalrule 的 Reconcile 吗？

[ronething]

Currently not, the previous implementations should not have considered this either.

Pull Request Overview

This PR adds support for the Apisix Global Rule by extending the ADC provider, cache interface, controllers, CRDs, and associated APIs. It introduces new methods for managing global rules in cache, a new ApisixGlobalRuleReconciler implementation, and updates to configuration samples and CRD definitions.

• Added global rule methods to the cache and provider interfaces.
• Integrated ApisixGlobalRule handling in the ADC client and created a new controller.
• Updated CRD defaults, API types, and configuration samples to support global rule functionality.

• Verify that changing 'secure_metrics' from an empty string to a boolean does not break existing configurations, and update the related documentation accordingly.

secure_metrics: false

	if obj.GetObjectKind().GroupVersionKind().Group == "apisix.apache.org" &&
	obj.GetObjectKind().GroupVersionKind().Version == "v2" {
	log.Debugw("api version is v2, skip sync", zap.Any("obj", obj))

[ronething]

Done.

[dspo]

v2 API 会有 gatewayProxy.Spec.Provider.Type == v1alpha1.ProviderTypeControlPlane 的情况吗？

[ronething]

Currently, there is only this type. we can consider whether it is necessary to differentiate.
