Increase per-region caching proxy capacity

Browse Source 
We want to start caching Kolla registry tarballs, but these
presently range upward of 4GiB each and need around 50GiB of
aggregate cache space. As a result, we'll increase the max cached
file size from 100MiB to 5GiB and the max cache content from 2GiB to
80GiB to support this.
