Describe the bug A few days ago, CartoDB changed its access model so that all base layers now require an API key: https://github.com/CartoDB/basemap-styles

To Reproduce Steps to reproduce the behavior:

  1. Create a new Dashboard & add a Geo Map Widget
  2. Select Map Layer Openstreet Positron or Openstreet DarkMatter
  3. Observe Watermark "API KEY REQUIRED"

Expected behavior There is an option with a predefined API Key or a setting where Users can enter their own API Key. Similar to the Google Maps layers:

Additional context API Keys are free with a fair use limit of 5 million requests per Month. But one has to create a CARTO account: https://carto.com/basemaps/
