Support the SetWriteDeadline and SetReadDeadline interfaces

[Mik-]

I'm using the new ResponseController, introduced in Go 1.20 to set a timeout on the response writer.
Your delegator did not respect the new interfaces SetWriteDeadline and SetReadDeadline.

Example:

rc := http.NewResponseController(w)
err = rc.SetWriteDeadline(time.Now().Add(5 * time.Second)) // returns ErrNotSupported

It would be nice, if the InstrumentHandlerDuration or InstrumentHandlerCounter would support this.

I'm currently using v1.18.0.
