* migration to new faster Infrastructure API and Codecs for method
@GET getAvailableStreams(UriInfo) on @Path {/streams}

New faster Infrastructure API works with NormizedNodeContext and
we are replacing getAvaliableStreams(UriInfo) method from RestconfService
to use NormalizedNodeContext.

* fix test suiteRestGetOperationTest
