    The port can belong to Operator or Module. hence used a common meta object in the portmeta.
This common meta object contains only
    - ports 
    - name
    - object
    
    The rest of Operator specific fields are in OperatorMeta and Module specific fields are
in ModuleMeta.

> Add support for adding modules in the DAG specified through property file and json file.
The sample json format is specified below.

>   "operators": [
>     {

>         "property1": "value1"

>           "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.
