mod_http_file_share: Add optional global quota on total storage usage Before, maximum storage usage (assuming all users upload as much as they could) would depend on the quota, retention period and number of users. Since number of users can vary, this makes it hard to know how much storage will be needed. Adding a limit to the total overall storage use solves this, making it simple to set it to some number based on what storage is actually available. Summary job run less often than the prune job since it touches the entire archive; and started before the prune job since it's needed before the first upload.
