New description:

 In current trunk, there is a "BucketCountingCrawler" whose job it is to
 count up how many shares are stored.

 I propose that this be replaced by using the leasedb to count files (a
 simple SQL COUNT query!), and at the same time to extend the storage
 server's abilities by letting it be able to add up the aggregate sizes of
 things as well as their number.

 This is part of an "overarching ticket" to eliminate most uses of crawler
 — ticket #1834.
