#8913: updating the logic for stale endpoint management
Original PR Body below
Description
Background:
This issue surfaces when we run the K8s for hyperv containers test https://github.com/kubernetes/kubernetes/blob/6381e6504ac210297e382c22029791267d440d9e/test/e2e/windows/service.go#L51 to reproduce you will need to set up testing cluster using capz windows-testing/capz/readme.md at master · kubernetes-sigs/windows-testing (github.com) and run this specific test. Else you could also look at test-grid logs for details on test failure: sig-windows-experimental Test Grid (kubernetes.io)
In the test Calico is unable to recognize a container endpoint is in ready state as it doesn't attach an endpoint as the logic is based on HNSEndpoint sharedContainers which are an empty field for hyperv containers. https://github.com/microsoft/hcsshim/blob/8beabacfc2d21767a07c20f8dd5f9f3932dbf305/internal/hns/hnsendpoint.go#L146
Calico logic to define a stale container needs to be updated. I do so by using the HNS Endpoint state attribute.
PR for hcshim: microsoft/hcsshim#2177
The change has been backported to hcsshim 0.11 and 0.12 and we here ingest the latest tag to ingest dependent changes.
This change was tested by running kubernetes e2e tests locally for both hyperv containers and process isolated containers. All tests pass.
