Scaffolding: Add success messeges

[am11]

Right after scaffolding a model or vm, when the create or edit forms are submitted successfully and request is redirected to the Index view, there is no success message displayed.

In Ruby (sometimes) on Rails, there is a div id='notice' in the default layout which displays the status of the previous transaction and scaffold complements its existence by saying flash[:notice] = "#{model_name} successfully created", where flash[:notice] is roughly equals to ViewBag["notice"].

Please consider introducing similar pattern to vNext.

Thanks!

Hi @am11 sorry for the long delay here. I've discussed with @prafullbhosale and he will investigate.
