Problem statement
We want to be able to offer shard and node level filtering for Query Insights - which requires the InTel team to collect $queryStats from both mongos, and mongod. For sharded clusters, we currently support queryStats collection on mongos's, but not at the mongod level.

Acceptance criteria
The output of this ticket should be a report on the performance of sharded clusters when queryStats is enabled on the mongod level. We should be able to look at this report and make a go/no-go decision on whether we can turn on, and collect queryStats from mongods in sharded clusters.
