Before this change, the per-host reservation size was computed
by the Planner. However, scheduling happens after planning,
so the Planner must assume that all fragments run on all
hosts, and the reservation size is likely much larger than
it needs to be.
This moves the computation of the per-host reservation size
to the BE where it can be computed more precisely. This also
includes a number of plan/profile changes.
