/* Renders a list of key values objets

mandatory config parameters:
rows: an object container where each propery is a key-value object we want to render
       var rows = {
           keyboard: {
               header: gettext('Keyboard Layout'),
               editor: 'Your.KeyboardEdit',
               required: true

optional:
disabled: setting this parameter to true will disable selection and focus on the
proxmoxObjectGrid as well as greying out input elements.
Useful for a readonly tabular display
