Add MemberId to from response header to the model.EtcdResponse. Ensure it's added to json response and visualized in the porcupine linearization.

Edit: Would be great to have this information showing in tooltip, for that we need https://github.com/anishathalye/porcupine/pull/39

Tasks:

Why is this needed?

Makes it easier to debug linearization failure
