[MapProxy] MBTiles: multiple grids stored in single tiles table

[Just van den Broecke]

Hi Oliver,

Ok, I now use GeoPackage caching, works like a charm. Need WMS and 
cannot change URLs. Also more metadata.

Best,

the tiles for the two grids are created in a single "tiles" table in a 
single sqlite file "my.mbtiles". I would expect two MBTiles files, named 
after the grids. Also if I leave "filename" out a single 
"my_mbtiles_cache.mbtiles" file is created. (Defining two MBTiles caches 
is a bit complicated now, as this would require renaming Layers).

GLOBAL_(WEB)MERCATOR . Possibly I should move to sqlite or geopackage 
caches, the latter storing more metadata and a single tiles table per 
grid...
