[JaydipGabani]

Fixes open-policy-agent/gatekeeper#2917

Gatekeeper counter part - open-policy-agent/gatekeeper#4115

Pull Request Overview

This PR adds status tracking functionality to external data providers in the Gatekeeper framework. The implementation adds status fields to Provider resources across multiple API versions to track provider pod status, errors, and operational state.

• Adds comprehensive status structures including ProviderStatus, ProviderPodStatusStatus, and ProviderError types
• Updates all API versions (v1alpha1, v1beta1, unversioned) with consistent status field implementations
• Generates supporting deepcopy and conversion functions for the new status types
