Please feel free to change reporter if you would like to.

In supervisor we're removing topology code when assignments for that supervisor has gone.
But there's valid scenario to need to keep the topology code though assignments for that supervisor is none, for example, rebalancing.

So it would be better for supervisor to keep topology code until topology has been killed (and all topology workers assigned to that supervisor are also killed).
