Set CacheMaxExpire to 1h

We want to limit the time we remember possibly broken index responses
which we sometimes receive from the pypi CDN. We cannot set this per
location, so this is a comprise between reducing the impact of bad eggs
in the cache and trying not to throw out the good eggs too fast.

# Pip sets Cache-Control: max-age=0 on requests for pypi index pages.
# This means we don't use the cache for those requests. This setting
# should force the proxy to ignore cache-control on the request side
