Container runtimes like CRI-O and containerd reuse the code by copying
it from Kubernetes. To have a single source of truth for the streaming
server we now move the already isolated implementation to the
k8s.io/kubelet staging repository. This way runtimes can re-use the code
without copying the parts.
