Pull Request Overview
This PR refactors resource monitoring to extract quota calculation logic into dedicated ResourceQuotaProvider implementations and adds Kubernetes support for resource monitoring. The changes separate concerns by moving resource limit/request determination out of snapshot providers into reusable quota providers.
Key changes:
- Introduces
ResourceQuotamodel andResourceQuotaProviderabstract base class for platform-agnostic quota retrieval - Creates
WindowsContainerResourceQuotaProviderandLinuxResourceQuotaProviderimplementations for existing platforms - Adds new
Microsoft.Extensions.Diagnostics.ResourceMonitoring.Kuberneteslibrary with Kubernetes-specific quota provider that reads from environment variables
