**What this PR does / why we need it**:
This is the first stab at supporting kube-proxy (userspace mode) on Windows
**Which issue this PR fixes** :
fixes#30278
**Special notes for your reviewer**:
The MVP uses `netsh portproxy` to redirect traffic from `ServiceIP:ServicePort` to a `LocalIP:LocalPort`.
For the next version we are expecting to have guidance from Microsoft Container Networking team.
**Limitations**:
Current implementation does not support DNS queries over UDP as `netsh portproxy` currently only supports TCP. We are working with Microsoft to remediate this.
