This change adds 2 options for windows: --forward-healthcheck-vip: If true forward service VIP for health check port --root-hnsendpoint-name: The name of the hns endpoint name for root namespace attached to l2bridge, default is cbr0 When --forward-healthcheck-vip is set as true and winkernel is used, kube-proxy will add an hns load balancer to forward health check request that was sent to lb_vip:healthcheck_port to the node_ip:healthcheck_port. Without this forwarding, the health check from google load balancer will fail, and it will stop forwarding traffic to the windows node. This change fixes the following 2 cases for service: - `externalTrafficPolicy: Cluster` (default option): healthcheck_port is 10256 for all services. Without this fix, all traffic won't be directly forwarded to windows node. It will always go through a linux node and get forwarded to windows from there. - `externalTrafficPolicy: Local`: different healthcheck_port for each service that is configured as local. Without this fix, this feature won't work on windows node at all. This feature preserves client ip that tries to connect to their application running in windows pod.
