How about moving it into DAG as this is specific to DAG. Component is more
general and is implemented by artifacts that are not part of DAG such as
security components.

> 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.
