`kubectl port-forward` now exits when a pod disconnects. This addresses `kubectl` user expectations that the Teleport Kubernetes proxy behave transparently, and identical to direct-to-Kubernetes. - Changed error stream copying to uni-directional (target -> source) in SPDY and WebSocket `forwardStreamPair()` functions - Added `WaitGroup` to SPDY `run()` enabling all port-forward streams to fully complete before returning - Added an integration test for Kubernetes port-forwarding with pod disconnection - Updated existing port-forward integration tests to allow and expect `ErrLostConnectionToPod` Fixes #54814
