[MapProxy] gdal2tiles's geodetic profile and mapproxy

The issue appears to be the res_factor.  The default of 2 for GLOBAL_GEODETIC only displays the bottom-left quadrant of the tile data created with gdal2tiles.py, but increasing this value to 4 shows all the data.  I tested this with globe data I cached from 0-3.

I will assume this is caused by the way gdal2tiles calculates their resolution, but I thought it was important to archive this info in case someone else runs into the problem.  Thanks for the help!

GLOBAL_GEODETIC is only defined till level 19. Add a new grid with base: GLOBAL_GEODETIC and num_levels: 22.
