[Tile-serving] Need tiles levels 0-10 for offline access

[Paolo Maffei]

Hopefully for zoom levels 0-10 we do not need an update strategy as it's
pretty hard something will change at that level (satellite images-wise at
least)

Any idea on where to find an easy way of generating tiles ourselves and
what actually is the effort involved (for example is z0-10 doable with a
modern quad core machine)?
