Description

AlertDefinitions need to change slightly to allow an object-ified "reporting" structure.

Example alerts.json

    {
      "name": "namenode_cpu",
      "label": "NameNode host CPU Utilization",
      "scope": "host",
      "source": {
        "type": "METRIC",
        "jmx": "java.lang:type=OperatingSystem/SystemCpuLoad",
        "host": "{{hdfs-site/dfs.namenode.secondary.http-address}}",
        "reporting": {
          "ok": {
            "text": "System CPU Load is OK"
          },
          "warning": {
            "text": "System CPU Load is Nearing Critical",
            "value": 70
          },          
          "critical": {
            "text": "System CPU Load is Critical",
            "value": 80
          }
        }
      }
    }

Example Heartbeat JSON:

   'alertDefinitionCommands':[  
      {  
         'alertDefinitions':[  
            {

               'enabled':True,
               'interval':1,
               'label':'HDFS Port Check',
               'name':'HDFS-Port',
               'serviceName':'HDFS',
               'source':{  
                  'port':0,
                  'reporting':{  
                     'critical':{  
                        'text':'TCP FAIL - {0:.4f} response on port {1}'
                     },
                     'ok':{  
                        'text':'TCP OK - {0:.4f} response on port {1}'
                     }
                  },
                  'type':'PORT'
               }
            }
         ],
         'clusterName':'c1',
         'commandType':'ALERT_DEFINITION_COMMAND',
         'hash':'0b1000cc35c3daf1bca1504d126a71bd',
         'hostName':'c6404.ambari.apache.org'
      }
   ],
   'cancelCommands':[
