[MapProxy] mapproxy and S3

[James Sewell]

Thanks,

Seems the S3 stuff is pretty broken in MapProxy for this use case.

I’ve made some updates which speed up the cache considerably (at the moment
it’s a boot session per tile I think) and expose some extra settings
(region name, max http pool connections) to make things easier.

I’ll PR next week.

Cheers,
James Sewell
