DMaaP adapter, updated job definition syntax

DMaaP adapter, updated job definition syntax

The filter syntax is updated so that measTypes are structured below measuredObjClass
The job definition is updated so that the output contains both topic and the kafka boostrap servers.
Graceful shutdown of Dmaap Adapter

Example of PM definition after the change:

{
   "filter":{
      "sourceNames":[
         "NodeA", "NodeB"
      ],
      "measObjInstIds":[

      ],
      "measTypeSpecs":[
         {
            "measuredObjClass":"NRCellCU",
            "measTypes":[
               "pmCounterNumber0"
            ]
         }
      ],
      "measuredEntityDns":[

      ]
   },
   "deliveryInfo":{
      "topic":"ouputTopic",
      "bootStrapServers":"localhost:9092"
   }
}
