We need to make sure all decisions in the planner that currently use number of nodes use number of instances if appropriate.
E.g.
- HashJoinNode.computeNodeResourceProfile() has a TODO.
- I think the broadcast/shuffle decision doesn't take into account mt_dop, which is wrong if we're broadcasting to multiple instances per fragment.
