mongo: fix status output in sharding initialization

The sharding initialization script was using rs.status() instead of the
correct sh.status() call when querying mongos. This results in the
following error message:

    mongos> rs.status()
    {
      "info" : "mongos",
      "ok" : 0,
      "errmsg" : "replSetGetStatus is not supported through mongos"
    }
Merge branch 'shard-status'
