[MapProxy] Render lower/higher zoom levels

[Martin Kokeš]

Okay, I added new grid:

grids:
  global_mercator_osm:
    base: GLOBAL_MERCATOR
    num_levels: 22

and redefined my cache to use:
grids: [global_mercator_osm, global_geodetic_sqrt2]

and got 14-21 zoom levels. Higher zooms are pretty interpolated, bu no matters. Still I'd prefer to have 8-21 zoom levels. Tried to play with max_shrink_factor, but still no luck.
