cmd/k8s-operator,k8s-operator/sessionrecording: support recording kubectl exec sessions over WebSockets (#12947)

cmd/k8s-operator,k8s-operator/sessionrecording: support recording WebSocket sessions

Kubernetes currently supports two streaming protocols, SPDY and WebSockets.
WebSockets are replacing SPDY, see
https://github.com/kubernetes/enhancements/issues/4006.
We were currently only supporting SPDY, erroring out if session
was not SPDY and relying on the kube's built-in SPDY fallback.

This PR:

- adds support for parsing contents of 'kubectl exec' sessions streamed
over WebSockets

- adds logic to distinguish 'kubectl exec' requests for a SPDY/WebSockets
sessions and call the relevant handler

Updates tailscale/corp#19821
