Description:
Info
When we test multiversion scenarios, the parameters set at the build variant level (like this one), are not being set during the instantiation of old mongod binaries (i.e. mongod-8.0, mongod-7.0, etc). According to this message, this prevents setting a parameter that could not exist on a mongod version. However, this is error-prone solution since some tests may expect a parameter to be set on all the mongod binaries of a cluster. For instance, we have had a test failure (the BF is linked to this ticket) since we expected all binaries on a cluster to have set this parameter.

Steps to Reproduce
Run this multiversion test locally from the master branch: buildscripts/resmoke.py run --storageEngine=wiredTiger --storageEngineCacheSizeGB=0.5 --dbpath=/tmp/testpath --mongodSetParameters='{internalQueryFrameworkControl: forceClassicEngine}' --jobs=1 --suite=sharding_last_lts_mongos_and_mixed_shards ./jstests/ sharding/query/lookup_targeting.js
