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

how does it translate into K8s request and limits?

max are limits, and baselines are requests

do you think it makes sense to reflect that in XML documentation here?

I think it should be dev stage initially. After one release (= one month) we can change it to normal. And in this case we don't have to bother with EnablePackageValidation because it is not enabled for dev packages:

Let me verify that. I would prefer to release it already in December as normal.
