 Description   
Original Downstream Change Summary

We added 4 new serverStatus metrics to count hits and misses in the classic and SBE plan caches. They are:

query.planCache.classic.hits
query.planCache.classic.misses
query.planCache.sbe.hits
query.planCache.sbe.misses

Description of Linked Ticket

Inspired by SERVER-64978, we should add two additional serverStatus metrics counters to accumulate plan cache hits and misses. christopher.harris@mongodb.com has confirmed this would be useful for product/field team.
