Added /api/v3/search_preview endpoint to use while the user types in the search box. It finds visualizations and tags, returning only the required information.

Parameters:

• q: search pattern (mandatory)
• limit: max results. 4 by default (first all the found tags and then visualizations)
• types: "derived,table,remote,tag" by default

Response example:

{
  "result": [
    {
      "type": "tag",
      "name": "spain",
      "url": "http://user.carto.com/dashboard/search/tag/spain"
    },
    {
      "type": "derived",
      "name": "Madrid traffic",
      "url": "http://user.carto.com/viz/107b672b-6f57-4a9e-b982-bbf1e041124a/map"
    }
  ],
  "total_count": 2
}

It includes visualizations/tags owned by or shared with the user, with any kind of privacy and locked/unlocked.
