Related to #6195

This change allows to configure when using the mode addLayerNamesMode=url which WMS properties should be used to fill the online resource name and the online resource description.

• resourceName: allowed values layerName (WMS layer name) | layerTitle (WMS layer title)
• resourceDescription : allowed values layerName (WMS layer name) | layerTitle (WMS layer title)

If these properties are not provided, the resource name or resource description are not filled automatically with the WMS information and the user should fill them.

This change doesn't affect the default addLayerNamesMode mode (resourcename).

Attached a screencast using the following configuration:

 "wmsResources": {
    "addLayerNamesMode": "url",
    "resourceName": "layerTitle"
  }
