Updated the patch. @StevenMPhillips, @jacques-n, if you guys can do a quick
review.
The cache code now uses the same file name and reads the metadata
appropriately. Note that as a result, v1 and v2 of the cache file can not
co-exist (and also means that Drill 1.3 and earlier are no longer forward
compatible).
