BUG 2412 - restconf @PUT updateConfigurationData method migration
* migration to new faster Infrastructure API and Codecs for method
@PUT updateConfigurationData(String, NormalizedNodeContext)
on @Path {/config/identifier}
New faster Infrastructure API works with NormizedNodeContext and
we are replacing updateConfigurationData method from RestconfService
to use NormalizedNodeContext.
