This host has migrated to tarballs.opendev.org, but rather than updating this caching rule, an audit of codesearch and a cursory look at several mirror logs has determined this wasn't ever really used. Since it is now on AFS, we could export this directly from the filesystem on mirror nodes and implicitly use AFS caching if we need to reinstate this.
