// these proxies allow the inter-connection of WebSocket and SPDY

// The stream translator proxy is used for the RemoteCommand
// subprotocol (e.g. kubectl exec, cp, and attach), and it connects
// the output streams of a WebSocket connection (e.g. STDIN, STDOUT,
// STDERR, TTY resize, and error streams) to the input streams of a
// SPDY connection.

// workload and, if that's the case, terminates special processing required for that type
// of workloads, such as auto-registration, health status updates, etc.
//
// If proxy represents a workload (be it auto-registered or not), WorkloadEntry resource
// will be updated to reflect that the proxy is no longer connected to this particular `istiod`
