Hi,

I think it is a good idea to have the object-replicator's failure info 
in recon like the other replicators.

I think the following info can be added in object-replicator in addition to 
"object_replication_last" and "object_replication_time".

If there is any technical reason to not add them, I can make it. What do 
you think?

{
    "replication_last": 1416334368.60865,
    "replication_stats": {
        "attempted": 13346,
        "empty": 0,
        "failure": 870,
        "failure_nodes": {"192.168.0.1": 3,
                          "192.168.0.2": 860,
                          "192.168.0.3": 7},
        "hashmatch": 0,
        "remove": 0,
        "start": 1416354240.9761429,
        "success": 1908
        "ts_repl": 0
    },
    "replication_time": 2316.5563162644703,
    "object_replication_last": 1416334368.60865,
    "object_replication_time": 2316.5563162644703
}

Cheers,
Hisashi Osanai
