[MapProxy] Cache with multiple grids

Thank you Oliver,
I currently defined dedicated caches with a single grid each, and merged
them in a further cascade cache with no duplicated storage
(disable_storage: true)
That worked fine for me: I tried with coverages too at the beginning but I
was getting full-extent tiles in the first layers too: e.g. a quarter of
the world at zoom 1. Furthermore I want to limit each component to a
different set of resolutions and that is probably a bit less
straightforward to achieve with a single grid + coverages.
(PS does this little bug or missing feature deserve a GitHub issue?)
thanks!!
