Cordova Metrics support

[edewit]

Windows android and iOS support, to test add sendMetricInfo in json:

{
            "pushServerURL": "<host url e.g http://server:port/ag-puhs>",
            "sendMetricInfo": true,

For testing windows be sure to add the windows page parameter:

{
     "message": {
      "alert": "Hello metrics",
      "windows": { 
          "page": "cordova" 
       }
     }

@sebastienblanc As discussed with @edewit to avoid compilation issue for ios plugin, we need AGPushPlugin.h to be modify to add @Property

+1 on iOS
I've used HelloWorld app tpo test it, i only had to change the push-config.json to included:
"sendMetricInfo": true,
Tested for background and newly launched app. Both cases send metrics ok.

PS: @edewit don't forget to put in your PR AGPushPlugin.h modified with chanelId property.
