    I saw some odd behavior I think is unrelated to this PR itself while testing.
    
    I tried to remove the threat triage rule, messed up, fixed it, and then borked my conf variable.  After recovering I was able to successfully test (and run THREAT_TRIAGE_REMOVE without breaking conf).
    
    ```
    [Stellar]>>> conf
    {
      "enrichment" : {
        "fieldMap" : {
          "geo" : [ "ip_dst_addr", "ip_src_addr" ],
          "host" : [ "host" ],
          "stellar" : {
            "config" : {
              "is_alert" : "source.type == 'bro'"
            }
          }
        },
        "fieldToTypeMap" : { },
        "config" : { }
      },
      "threatIntel" : {
        "fieldMap" : {
          "hbaseThreatIntel" : [ "ip_src_addr", "ip_dst_addr" ]
        },
        "fieldToTypeMap" : {
          "ip_src_addr" : [ "malicious_ip" ],
          "ip_dst_addr" : [ "malicious_ip" ]
        },
        "config" : { },
        "triageConfig" : {
          "riskLevelRules" : [ {
            "name" : "Abnormal DNS Port",
            "rule" : "source.type == \"bro\" and protocol == \"dns\" and ip_dst_port != 53",
            "score" : 10.0
          } ],
          "aggregator" : "MAX",
          "aggregationConfig" : { }
        }
      },
      "configuration" : { }
    }
