A way to read custom properties set by the node itself

[Proryanator]

I'm using v1.2.1 right now, just a heads up!

I'm aware that you can set custom properties from the node, as seem here from selenium-server -role node -help:

...
-custom
      <String> : comma separated key=value pairs for custom grid extensions. 
      NOT RECOMMENDED -- may be deprecated in a future revision. Example: 
      -custom myParamA=Value1,myParamB=Value2
...

These would showup in a node GET request if you send one to it. Look about mid-way, you'll see a json bit with "custom": {}, which is blank but, if it were set, I don't believe that Talk2Grid supports reading these values.

      ],

      },

    },

  },
  "success": true
}

I looked in the classes HubConfiguration and NodeConfiguration to see if it has some property like 'getCustom' but I did not see it.

Is this something that could be easily added in? Or if this feature exists, I wonder where it is? :)
