Deprecate thread_scheduling_group in favor of scheduling_group

scheduling_group provides better functionality (inheritance along continuation chains, submit_to() calls, and even RPC) and better performance as it doesn't require a high precision timer per thread. It is time to deprecate thread_scheduling_group with a view to retiring it later. Message-Id: <[email protected]>
