> Add support for adding modules in the DAG specified through property file and json file.
The sample json format is specified below.
> {code}
> {
>   "operators": [
>     {
>       "name": "operator1",
>       "class": "com.datatorrent.lib.operator.Input",
>       "properties": {
>         "property1": "value1"
>       }
>     },
>     {
>       "name": "module1",
>       "class": "com.datatorrent.module.Module1",
>       "properties": {
>         "property1": "value1"
>       }
>     },
>   ],
>   "streams": [
>     {
>       "name": "s1",
>       "source": {
>         "operatorName": "operator1",
>         "portName": "output"
>       },
>       "sinks": [
>         {
>           "operatorName": "module",
>           "portName": "input"
>         }
>       ]
>     }
>   ]
> }
> {code}
> For this to work, we will need to support adding module in DAG through property file
API.
> This will allow external tools to visually construct the DAG containing modules.
