Self host map tiles
Let's stop using open streep map servers and build an image with tiles (not with all zoom level of course...) fo rus.
Also switch to vector tiles and https://github.com/alex3165/react-mapbox-gl
- Move from leaflet to mapbox in the front
- Update Nginx to serve the tiles directly
- Make sure the tiles are only accessible to users from the website
- Build an image for the whole world and post it to docker-hub
