Enable/disable product row action added

Do I need to add any tests for this?

Not easy, FYI, the request is sent here https://github.com/akeneo/platform/blob/pim-1.2/src/Oro/Bundle/DataGridBundle/Resources/public/js/datagrid/action/abstract-action.js#L189 

I think we could enhance this part in the future to provide new options on actions.

You're right, really not ideal to use GET in this case as we update the data on server side, but it's ok until we enhance row actions.
