Bug 3024 - Restconf PUT exception when top level node is from
augmentation

* added check for PUT into JsonNormalizedNodeBodyReader. If method is
PUT then data are unwraped from augmentations/choice nodes
* added wrapping of augmentation nodes when using XmlNormalizedNodeBodyReader
* commented out check for namespace in createConfigurationData (it should be
moved to parse stage)
* both XmlNormalizedNodeBodyReader and JsonNormalizedNodeBodyReader
should now produce the same normalized node data and paths for
equivalent XML and JSON input.
