BUG 2412 - restconf @GET getModule(identifier,uri) method migration
* migration to new faster Infrastructure API and Codecs for method
@GET getModules(String,UriInfo) on @Path {/modules/identifier}
New faster Infrastructure API works with NormizedNodeContext and
we are replacing first method getModule(URI) from RestconfService
to use NormalizedNodeContext.
* add yang models for fix tests (mountpoint tests - TestUtility
loads modules from local directory only)
