Description
SBE multi planner currently counts every read: index seek/scan and collection seek/scan as a "read" and the main measure of SBE plan in multi planner is reads per doc.
Because of this, plan with fetch needs to be twice as efficient as plan without fetch to be selected. In classic, noFetch bonus is much smaller.
To make reads more comparable with classic's works and avoid this problem, we should not count fetch stage in trial run tracker.
