cmd/k8s-operator,ssh/tailssh,tsnet: optionally record kubectl exec sessions
The Kubernetes operator's API server proxy, when it receives a request
for 'kubectl exec' session now reads 'RecorderAddrs', 'EnforceRecorder'
fields from tailcfg.KubernetesCapRule.
If 'RecorderAddrs' is set to one or more addresses (of a tsrecorder instance(s)),
it attempts to connect to those and sends the session contents
to the recorder before forwarding the request to the kube API
server. If connection cannot be established or fails midway,
it is only allowed if 'EnforceRecorder' is not true (fail open).
