BUG 2412 - restconf getOperations method migration
* migration to new faster Infrastructure API and Codecs for method
@GET getOperations(UriInfo) on @Path {/operations}
New faster Infrastructure API works with NormizedNodeContext and
we are replacing first method getModule(URI) from RestconfService
to use NormalizedNodeContext.
BUT we are not able follow specification for migration in this case
because, we have to change restconf-netconf yang schema before.
