    Show the sum of every policy's amount in /recon/async

    After the release of Swift ver. 2.0.0, some recon responses do not
    show each policy's information yet. To make things worse, some recon
    results only count on policy-0's score, therefore the total is not
    shown in the recon results.

    With this patch, async_pending count of recon results becomes
    policy-aware. Suppose a number of async_pending files for policy-0 is 2
    and a number for policy-1 is 3, recon sums up every policy's amount
    as follows.

    $ curl http://<host>:<port>/recon/async
    {"async_pending": 5} # It showed 2 before this commit
