Product "metaData" attribute

In managing a first party ordering site, custom product settings to control display, seo, analytics etc can now be added within a "Meta data" section of "Product Specifications"

The input supports a key/value pairing, which will appear in the menu model as below;

{
    "metadata": [
      {
        "key": "highlight",
        "value": "true"
      },
      {
        "key": "seo.title",
        "value": "Classic Burger"
      },
      {
        "key": "text_color",
        "value": "#222222"
      }
    ]
}
