The TODOs were added back in the Queens/Pike timeframe [1][2]
but at this point there probably isn't much value in resolving
those TODOs by adding a skip_filters kwarg to the scheduler
especially since [3] changed the method to not support nested
resource provider allocations so the minimal duplication with
what we do in the scheduler in the non-force evacuate/live migrate
cases is sufficient.
