Report a histogram of error codes rather than just an error counter in serverStatus

      The idea is to replace something like

      errors: 5

      with something more like

      errors: {
    26: 1,  /* NamespaceNotFound */
    50: 2,  /* MaxTimeMSExpired */
    59401: 2,  /* anonymous error code */
}

      We could do that both for this top level "asserts" section:

      "asserts" : {
                "regular" : 0,
                "warning" : 0,
                "msg" : 0,
                "user" : 0,
                "tripwire" : 0,
                "rollovers" : 0
        },

      But also for the "commands" section, or anywhere else we accumulate errors:

                      "commands" : {
                        "buildInfo" : {
                                "failed" : NumberLong(0),
                                "total" : NumberLong(3)
                        },
                        "createIndexes" : {
                                "failed" : NumberLong(0),
                                "total" : NumberLong(3)
                        },
                        "find" : {
                                "failed" : NumberLong(0),
                                "total" : NumberLong(21)
                        },

      This will help gather more insight into what kinds of things are going wrong. For example if we start to see a lot more of a particular error code after upgrading to a new version.
