Daisuke Morita f8fa1a9234 Show each policy's information on quarantined files in recon
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.

This patch makes the count of quarantined files policy-aware for recon
requests. Suppose a number of quarantined objects for policy-0 is 2
and a number for policy-1 is 3, recon sums up every policy's amount
and shows information for each policy as follows.

$ curl http://<host>:<port>/recon/quarantined
{"accounts": 0, "containers": 0, "objects": 5, "policies": {"0":
{"objects": 2}, "1": {"objects": 3}}}

Moreover, this patch adds stats for each policy in CLI output.
