While working on SERVER-87634 an issue came up with over-reporting metrics in lookup_query_stats.js. This seems to be caused by the curOp metrics block inside of collectQueryStats(). In the jstest, there are 5 tests being run, each one running a query with a different scan, and then runs explain with every verbosity. The second test's assertion for curScannedObjects fails, regardless of what order the tests are being run. Thus, to avoid over-reporting right now we collect directly with collectQueryStatsMongod instead of collectQueryStats() so that we can skip curOp->debug().setPlanSummaryMetrics() and CurOp::setEndOfOpMetrics(). To reproduce the issue, replace

collectQueryStatsMongod(opCtx, expCtx, std::move(curOp->debug().queryStatsInfo.key));

 inside of run_aggregate() with

collectQueryStats(opCtx, expCtx, explainExecutor, nullptr);

compile, and then run 

buildscripts/resmoke.py run --suites=aggregation jstests/aggregation/sources/lookup/lookup_query_stats.js  --additionalFeatureFlags=featureFlagQueryStats
