[New Feature] Topic metadata

You can now add metadata to Topics via API (only). Please refer to the API documentation on making API calls: https://getchamp.net/guides/api/

The property for the Topic metadata is... metadata. The API will expect a hash for this data:

{
  forum_id: 123,
  title: "My title",
  metadata: {
    product_id: 100
  }
}

Making an API call with the above JSON payload will insert a metadata with a key of product_id and a value of 100.

With this, you can also query Topics via the JavaScript endpoint at /community/champ/latest.json?metadata[key1]=value

You can also chain the metadata conditions as well:
/community/champ/latest/topics.json?metadata[key1]=value&metadata[key2]=value

So using the above example, you can query for that particular topic like so:
https://yourstore.com/community/champ/latest/topics.json?metadata[product_id]=100

Please report bugs :-)
