Fix geosolutions-it#1329. Use layer params in GFI

 - Now the getFeatureInfo gets the params from the layer.
 - The params are overridable by the params property of the feature info (the tool was using them only in the previous implementation)
 - Fixed the excludeParameter filter to add parameter properly (before it was sending to the server a json called params)
 - Add a unit test for this
